Description Richard Riley Gress 2014-01-03 00:40:16 UTC
Created attachment 120681 [details]
The output of the terminal command `aplay -l`

This is a sound chipset that is not configurable in Linux at this time. The sound card is not recognized by the operating system's software (e.g. Phonon will only recognize "Dummy output" and Alsamixer will label it "Generic"), but the hardware is recognized.

Comment 7 Richard Riley Gress 2014-01-04 02:20:18 UTC
Correct: neither of the two HDMIs are being used. Plugging stereo speakers or headphones directly into the green jack on the onboard sound card or into the front port results in a buzzing noise. Microphones, of course, wouldn't be detected anyway. I blacklisted the snd-intel-hdmi module at one point, but it is not blacklisted anymore. And the same behavior was there before then.

https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/plain/Documentation/sound/alsa/HD-Audio.txt

try early patching 

with hint

trigger_sense=false




- jack_detect (bool): specify whether the jack detection is available
  at all on this machine; default true

- trigger_sense (bool): indicates that the jack detection needs the
  explicit call of AC_VERB_SET_PIN_SENSE verb

Alsa hardware driver hint

 - Created onboard-audio.fw in /lib/firmware

 - Added the line `options snd-hda-intel patch=onbaord-audio` to /etc/modprobe.d/alsa-base.conf

 - Rebooted, still just "Dummy Output" in Phonon and same behavior as before
Comment 10 Raymond 2014-01-05 05:20:51 UTC
did you hear any sound ?

speaker-test -c2 -t wave -D hw:1,0








if you have three hda controller


you can change the order of the card by

options snd-hda-intel index=1,0,2





post the output of

pactl list

pactl stat
Comment 11 Richard Riley Gress 2014-01-05 13:43:13 UTC
There is still no sound except for the same monotone I mentioned before. Changing the order of the cards also did not do anything.

Comment 14 Raymond 2014-01-06 01:16:03 UTC
do your computer chassis have a HDA front audio panel which support jack detection ?

http://www.intel.com/support/motherboards/desktop/sb/cs-015851.htm

you can disable jack detection by hint

jack_detect = 0
Comment 15 Richard Riley Gress 2014-01-06 15:13:15 UTC
My computer has none of those Desktop Boards; it is an A55M-P33 built by MSI. In any case, disabling jack detection did not do anything. I do not know if I set up my hint file correctly. Do new hints go on a new line below previous hints?

/lib/firmware/onboard-audio.fw :

trigger_sense=false

Comment 16 Raymond 2014-01-07 03:18:15 UTC
can you post the output of alsa-info.sh after early patching 

and pulseaudio verbose log

check the response of hda unsol event when headphone is plugged and unplugged in system log by enable tracepoints

Tracepoints
~~~~~~~~~~~
The hd-audio driver gives a few basic tracepoints.
`hda:hda_send_cmd` traces each CORB write while `hda:hda_get_response`
traces the response from RIRB (only when read from the codec driver).
`hda:hda_bus_reset` traces the bus-reset due to fatal error, etc,
`hda:hda_unsol_event` traces the unsolicited events, and
`hda:hda_power_down` and `hda:hda_power_up` trace the power down/up
via power-saving behavior.

Enabling all tracepoints can be done like
------------------------------------------------------------------------
  # echo 1 > /sys/kernel/debug/tracing/events/hda/enable
------------------------------------------------------------------------
then after some commands, you can traces from
/sys/kernel/debug/tracing/trace file. For example, when you want to
trace what codec command is sent, enable the tracepoint like:
------------------------------------------------------------------------
  # cat /sys/kernel/debug/tracing/trace
Comment 27 Richard Riley Gress 2014-01-16 23:10:04 UTC
I ran the command "# echo 1 > /sys/kernel/debug/tracing/events/hda/enable", rebooted, and then ran the following command twice, once with headphones unplugged from the front of the computer (see attachment 'tracept1.log') and once with them plugged in (see attachment 'tracept2.log'): "# cat /sys/kernel/debug/tracing/trace"

Oh and all the other changes I made, like making driver hints, I undid.

 if you specifiy hint Jack_detect=0 

phantom Jack controls will be created instead of headphone or line out Jack controls

and auto mute control will not be created 

if you find HDMI phantom Jack, this mean your early patching apply to HDMI codec instead of alc887vd

Your observations are correct; however I will say that the Sound Blaster is doing very well in the system and is producing some high quality sound, at least stereo, which is all I can test. I don't know why so many subdevices are listed.

the driver need to pre-allocate memory for Dma buffer for each subdevices

Common parameters for top sound card modules
  --------------------------------------------

    Each of top level sound card module takes the following options.

    index	- index (slot #) of sound card
		- Values: 0 through 31 or negative
		- If nonnegative, assign that index number
                - if negative, interpret as a bitmask of permissible
		  indices; the first free permitted index is assigned
		- Default: -1
    id		- card ID (identifier or name)
		- Can be up to 15 characters long
		- Default: the card type
		- A directory by this name is created under /proc/asound/
		  containing information about the card
		- This ID can be used instead of the index number in
		  identifying the card
    enable  	- enable card
		- Default: enabled, for PCI and ISA PnP cards

I have doubt about the bandwidth of pcie bus allow 256 streams  of 8 channels audio can be run at the same time

you have  to send email to the author to add your Pci subsystem Id to the driver if it is working as expected

https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/tree/sound/pci/ctxfi/ctatc.c


do you mean pulseaudio still not select your creative sound card as default sink ?
Comment 54 Takashi Iwai 2014-03-07 10:54:53 UTC
It seems that some radeon chips don't give the proper value for pin-sense verb but always return -1.  This should be the reason of the false detection.
If that's the case, the patch attached below should fix the false detection of non-plugged HDMI device.

Regarding 256 substreams of ctxfi: it's no bug but the expected behavior.  The emu20k1 chip supports the matrix-style mixing of the whole 256 streams, thus there is no reason to restrict in the driver side.  Besides, the allocation would fail if you'd try to use the whole 256x8 substreams, so the driver would return an error in anyway before reaching the hardware limit.

Fix aptch for AMD HDMI false detection
Comment 56 Takashi Iwai 2014-03-07 11:33:49 UTC
I found that 3.14-rc5 has a few fixes in radeon driver regarding the audio, and looking back at alsa-info.sh output you attached in comment 52, the HDMI jack detection was actually fixed there.  So the patch in comment 55 can be disregarded.

If you still have a problem with HDMI jack detection in the audio side with 3.14-rc5+ kernel, let me know.
Comment 57 Raymond 2014-03-07 12:01:00 UTC
 you can disable HDMI audio and use HDMI display

xrandr --output HDMI-0 --set audio off


seem pulseaudio did not save the setting of default sink

https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1256511

you may need to set the default sink in default.pa if your sound card does not support Jack detection
Comment 58 Takashi Iwai 2014-03-07 12:37:56 UTC
The misdetection of HDMI audio is a bug, and should have been fixed with 3.14-rc5.  If not, please speak up.

Apologies for the extraneous comment 60.
Comment 62 Richard Riley Gress 2014-03-07 21:06:34 UTC
At the end of /etc/pulse.default.pa there is this:

### Make some devices default
#set-default-sink output
#set-default-source input

So no default sink?
Comment 63 Raymond 2014-03-09 03:38:35 UTC
the default sink/source is controlled by module-swith-on-port-available

this module switch to another port when the port is not available (e.g. headphone is unplugged)

the availability of the ports of line out jacks of your creative sound card and onboard alc887 are unknown

So, I'm really confused.  Could you clarify concisely what's actually not working as expected?  There are way too many distracted comments in this thread...

My Realtek ALC877-VD onboard audio is not working. When I plug in headphones or speakers, there is a high-pitched, continuous noise. The card is listed as 'HD-Audio Generic' in Alsamixer. All the other information is attached.
Comment 67 Takashi Iwai 2014-04-30 06:15:24 UTC
OK, for concentrating only on ALC877-VD issue, let's forget about others for now.
At best, plug off your SB X-Fi board to reduce the confusion while testing.

First off, check the outputs of alsa-info.sh at plugging / unplugging the headphone jack.  The 'Headphone Jack' state must change accordingly, and the rear line-out jack (NID 0x14) must change its control between 0x40 and 0x00.  Confirm that this works properly.

Then check the outputs from the front headphone and the rear line-out jacks.  Do you get noise even if you don't play anything?  If so, and no loopback is enabled (e.g. "Mic Playback Volume" and "Mic Playback Switch"), it's likely a hardware issue.  But, we can still continue to check in details.

For example, try to mute the loopback on NID 0x0c and 0x0f:

  hda-verb /dev/snd/hwC1D0 0x0c SET_AMP 0x7180
  hda-verb /dev/snd/hwC1D0 0x0f SET_AMP 0x7180

where /dev/snd/hwC1D0 depends on the system setup.  If your HD-audio controller is assigned to another card slot, use the corresponding device appropriately.

If you get the noise still at this point, give alsa-info.sh output again.
Comment 68 Richard Riley Gress 2014-04-30 13:33:23 UTC
After I unplugged the X-Fi, I ran the alsa info script with (http://paste.ubuntu.com/7366237) and without (http://paste.ubuntu.com/7366240) headphones plugged in. There seems to be no support for detecting whether or not the headphones are plugged in. Running a `diff` for the two files produces nothing other than...

 $ diff after.txt before.txt

 457c457
 <   Amp-Out vals:  [0x80 0x80]
 ---
 >   Amp-Out vals:  [0x00 0x00]

The sound is present, with speakers or headphones plugged in to either jack. It begins during boot time, but not immediately.

`aplay -l` lists the card as "card 0, device 0", so I incorporated /dev/snd/hwC0D0 into your command and muted the loopback. At this point the sound was still present so I ran the info script again (http://paste.ubuntu.com/7366307)
Comment 69 Takashi Iwai 2014-04-30 14:08:43 UTC
OK, and the volume of the noise changes with either "Headphone" and "Speaker" mixer volume control, right?  To be sure, lower "Front Mic Playback Volume" and "Rear Mic Playback Volume" to zero, too.

The fact that the headphone jack detection doesn't work worries me whether your front panel is connected properly.  It's often wrongly connected as an AC97 panel, which is incompatible with HD-audio.  Nevertheless, this still shouldn't result in the static noise when all loopback channels are muted.

Also, such a noise can be a result of CPU freq changes.  Try to adjust it if it really matters.
Comment 70 Richard Riley Gress 2014-04-30 15:16:57 UTC
The volume of the noise remains unaffected by lowering any of the Playback Volumes in alsamixer. However, small, lower-pitched "ticks" can be heard as these Playback Volumes are adjusted. Using KDE's mixer has this effect, too.

As far as I can tell, the front panel is configured properly, though I've tried both the front and back plugs with exactly the same results. There's a cable in the machine that connects the motherboard to the small USB/headphone/mic front board. One end attaches to said front board, and the other end is a dual connector: one for AC'97, and the other for HD-AUDIO. Right now, the HD-AUDIO connection is plugged in to the proper AUDIO jack on the motherboard.

If by CPU frequency changes you mean overclicking or anything of that sort, I haven't messed around with that at all. There is a utility in the BIOS to do this that hasn't been touched.
Comment 71 Takashi Iwai 2014-04-30 15:44:37 UTC
What about Master, Headphone or other mute switch?  Does this shut up the noise?

I spoke of the normal CPU freq control, BTW.  It's known that some boards showed problems on the audio output when the CPU frequency changes dynamically even within the normal frequency ranges.  It's just a bad hardware design.
Comment 72 Richard Riley Gress 2014-04-30 16:06:43 UTC
Muting anything and everything in alsamixer or KDE's mixer does nothing to stop the noise. And the A55M-P33 which I am using does use Independent Dynamic Core Technology... there's nothing about it specifically in the BIOS, but it's listed next to AMD Cool'n'Quiet on the manufacturer's info page.

http://us.msi.com/product/mb/A55MP33.html

AMD Cool'N'Quiet was disabled in BIOS when I checked. Not sure if that did anything about that Independent Dynamic Core Technology, though.
Comment 73 Takashi Iwai 2014-04-30 16:09:03 UTC
If the mute doesn't work at all, it really smells like a hardware problem.
That is, the noise comes between the codec pin output and the actual jack, which is out of the control by software.
Comment 74 Takashi Iwai 2014-04-30 16:10:08 UTC
BTW, one last thing I can think of is to try model=generic option to snd-hda-intel module for skiping any vendor-specific codec setups.
Comment 75 Richard Riley Gress 2014-06-21 14:30:12 UTC
Closing because it was probably a hardware issue.
