dmesg with Linux 4.5

There is no "error DSP boot timeout" with Linux 4.5, however audio still not working (no sound adapters detected). "Baytrail Audio Port: ASoC: no backend DAIs enabled for Baytrail Audio Port" error message get repeated many more times in comparison with Linux 4.4.

Please look into attached dmesg.

dmesg with 4.5 and acpi_ipc_irq_index = 0

With acpi_ipc_irq_index = 0 (/sound/soc/intel/atom/sst/sst_acpi.c) firmware downlading seems successful:

Hundreds of "no backend DAIs enabled for Baytrail..." errors in dmesg with Asus T100-CHI starting with kernel 4.5.0-rc4 through 4.6-rc1-next.  CHI Uses rt5640 also.  There is a dmesg posted for bug#114561 with other details.

+ Vinod whose team own the driver.

Thanks for your email

I am attending ELC-NA, pls expect delayed response

This issue is being handled in #117141.

Can you attach the output of dmidecode, so that the DMI system identification can be added to the quirk-table in fix patch-set attached to that bug?
Comment 9 Paul Mansfield 2016-06-15 16:26:23 UTC
I am hoping for progress on this as I think this might solve the problem with broken sound on the Toshiba Click Mini as well.
Comment 10 Sachin Mokashi 2016-06-21 06:23:28 UTC
The following error about the missing backend DAI is due to the missing Alsamixer settings:

[   23.165318]  Baytrail Audio Port: ASoC: no backend DAIs enabled for Baytrail Audio Port

In this driver we use DPCM, which means that you have to route Front End
to a BackEnd and then only you can open a device. Without linking to BE it
will fail.

Would you please post the output of the command "aplay -l" to check if a sound card is getting created or not. 

If it is getting created, the output of "aplay -l" should look something like:

card 0: baytrailcraudio [baytrailcraudio], device 0: Baytrail Audio (*) []
   Subdevices: 1/1
   Subdevice #0: subdevice #0

If sound card is getting created, you can proceed with executing the following amixer commands:

For Playback:

#DSP routing
amixer -c0 sset 'codec_out0 mix 0 pcm0_in' on
amixer -c0 sset 'media0_out mix 0 media1_in' on
amixer -c0 sset 'media1_in Gain 0' 80% 
amixer -c0 sset 'media1_in Gain 0 Ramp Delay' 50
amixer -c0 sset 'media1_in Gain 0' off
amixer -c0 sset 'pcm0_in Gain 0' 80% 
amixer -c0 sset 'pcm0_in Gain 0 Ramp Delay' 50
amixer -c0 sset 'pcm0_in Gain 0' off
amixer -c0 sset 'codec_out0 Gain 0' 80%
amixer -c0 sset 'codec_out0 Gain 0 Ramp Delay' 50
amixer -c0 sset 'codec_out0 Gain 0' off

#Codec routing
amixer -c0 sset "DAC MIXL INF1" on
amixer -c0 sset "DAC MIXR INF1" on
amixer -c0 sset "Stereo DAC MIXL DAC L1" on
amixer -c0 sset "Stereo DAC MIXR DAC R1" on
amixer -c0 sset "SPK MIXL DAC L1" on
amixer -c0 sset "SPK MIXR DAC R1" on
amixer -c0 sset "SPOL MIX SPKVOL L" on
amixer -c0 sset "SPOR MIX SPKVOL R" on
amixer -c0 sset "SPOL MIX DAC L1" on
amixer -c0 sset "SPOR MIX DAC R1" on
amixer -c0 sset "Speaker L" on
amixer -c0 sset "Speaker R" on
amixer -c0 sset "Headphone" off
amixer -c0 sset "Ext Spk" on

Hope this helps!

Ok. Sound card is getting created. Did you do the alsa-mixer settings as mentioned? Are you still seeing No-Backend DAIs found error messages?


Also, We have merged quite a few patches upstream, can you please test the upstream kernel https://git.kernel.org/cgit/linux/kernel/git/broonie/sound.git for-next branch and upstrem fw repo https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/

With this branch https://github.com/plbossart/sound/commits/topic/v4.8-fixes and two commits mentioned above audio playback is working. As I understand this changes is heading upstream anyway so I close this report.
