If it's AD1981*, you may have "Line Jack Sense" and "Headphone Jack Sense" mixer switche. Toggle them on/off. Also, if you have "External Amplifier" mixer switch, turn it on. Or, unmute/raise "Master Mono" and "Headphone" mixer controls if exist. Thanks for your help! But unfortunately there is still nothing coming from the speaker. The codec is "Analog Devices AD1981B" and it has the "Line Jack Sense", the "Headphone Jack Sense" and the "External Amplifier" mixer switches. But changing them doesn't make sound work. "Master Mono" and "Headphone" mixer controls don't help either. (btw the OSS-module i810_audio works) When I run alsaconf the following is writen in the syslog file: udev[3636]: removing device node '/dev/mixer' udev[3638]: removing device node '/dev/snd/controlC0' udev[3640]: removing device node '/dev/snd/pcmC0D4p' udev[3642]: removing device node '/dev/snd/pcmC0D3c' udev[3644]: removing device node '/dev/snd/pcmC0D2c' udev[3646]: removing device node '/dev/snd/pcmC0D1c' udev[3648]: removing device node '/dev/adsp' udev[3679]: removing device node '/dev/snd/pcmC0D0p' udev[3681]: removing device node '/dev/snd/pcmC0D0c' udev[3683]: removing device node '/dev/dsp' udev[3685]: removing device node '/dev/audio' udev[3732]: removing device node '/dev/snd/timer' udev[4243]: configured rule in '/etc/udev/rules.d/udev.rules[61]' applied, 'timer' becomes 'snd/%k' udev[4243]: creating device node '/dev/snd/timer' kernel: PCI: Found IRQ 11 for device 0000:00:1f.5 kernel: PCI: Sharing IRQ 11 with 0000:00:1f.3 kernel: PCI: Sharing IRQ 11 with 0000:02:00.1 kernel: PCI: Setting latency timer of device 0000:00:1f.5 to 64 kernel: intel8x0_measure_ac97_clock: measured 55089 usecs kernel: intel8x0: clocking to 48000 udev[4317]: configured rule in '/etc/udev/rules.d/udev.rules[59]' applied, 'pcmC0D4p' becomes 'snd/%k' udev[4317]: creating device node '/dev/snd/pcmC0D4p' udev[4319]: configured rule in '/etc/udev/rules.d/udev.rules[59]' applied, 'pcmC0D3c' becomes 'snd/%k' udev[4319]: creating device node '/dev/snd/pcmC0D3c' udev[4321]: configured rule in '/etc/udev/rules.d/udev.rules[59]' applied, 'pcmC0D2c' becomes 'snd/%k' udev[4321]: creating device node '/dev/snd/pcmC0D2c' udev[4323]: configured rule in '/etc/udev/rules.d/udev.rules[59]' applied, 'pcmC0D1c' becomes 'snd/%k' udev[4323]: creating device node '/dev/snd/pcmC0D1c' udev[4325]: creating device node '/dev/adsp' udev[4327]: configured rule in '/etc/udev/rules.d/udev.rules[59]' applied, 'pcmC0D0p' becomes 'snd/%k' udev[4327]: creating device node '/dev/snd/pcmC0D0p' udev[4329]: configured rule in '/etc/udev/rules.d/udev.rules[59]' applied, 'pcmC0D0c' becomes 'snd/%k' udev[4329]: creating device node '/dev/snd/pcmC0D0c' udev[4364]: creating device node '/dev/dsp' udev[4366]: creating device node '/dev/audio' udev[4368]: configured rule in '/etc/udev/rules.d/udev.rules[57]' applied, 'controlC0' becomes 'snd/%k' udev[4368]: creating device node '/dev/snd/controlC0' udev[4370]: creating device node '/dev/mixer' Please show /etc/asound.state (or something else on debian). I still suspect it's a mixer configuration issue. Also attaching the contents of /proc/asound/card0/codec97#0/* files would be helpful, too. Created attachment 6139 [details]

Try running speaker-test speaker-test -c2 -Dplug:front speaker-test -c4 -Dplug:surround40 speaker-test -c6 -Dplug:surround51 If sound comes out, please tell use which speaker speaker-test thinks it is outputting from. Also, while the test in running, try toggling external amp using the M key in alsamixer. I tried running speaker-test, but there is no sound coming out :-( (using kernel 2.6.14) There are multiple clues on the Web that many laptops using this sound chipset must mute (in alsamixer) the 'external amplifier' to be able able to hear sound. For example, this is the case of my laptop (Vaio VGN-B1VP). This may be the issue here. > mute (in alsamixer) the 'external amplifier' to be able able to hear sound
I'm sorry, but that doesn't help.
Any improvement in later ALSA releases? With kernel 2.6.15.1 there is no difference. I tested KANOTIX 2005-04 with alsa (alsa-lib 1.0.10, kernel 2.6.14.5). There the sound worked. hmm... Turn off 'Headphone Jack Sense' and 'Line Jack Sense' swithes. I have an X31 for years, and have never noticed a single sound problem. I'm running 2.6.15, fc5t2. > Turn off 'Headphone Jack Sense' and 'Line Jack Sense' swithes.
Great, sound now works! Many thanks!
> Turn off 'Headphone Jack Sense'
that's the guilty switch on a Toshiba Satellite A40 too: sound was ok on K2.4.x
but no sound as I switched to K2.6.x. None of the ac97_quirk has any effect.
amixer sset 'Headphone Jack Sense' off && alsactl store
did the trick
thanks!
As the reporter says, this has been fixed, so I'm closing it. |
Most recent kernel where this bug did not occur: With 2.6.10 I had no problems Distribution: Debian Sarge Hardware Environment: Thinkpad X31 output of "cat /proc/asound/cards": 0 [I82801DBICH4 ]: ICH4 - Intel 82801DB-ICH4 Intel 82801DB-ICH4 with AD1981B at 0xc0000c00, irq 11 Software Environment: alsa-base 1.0.8-7 debian package Problem Description: You can play music e.g. with xmms or noatum as usual. But there is nothing coming from the speaker. There is also no hint in syslog. Kmix also works as usual (but the speaker keeps silent). Running alsaconf doesn't solve the problem. 2.6.13-rc5 had the same problem. With 2.6.10 sound works. Steps to reproduce: My .config: http://ro-wetter.dyndns.org/pics/.config
