Sound Intel SST, Bay Trail SoC, Asus T200TA. Kernel modules, ALSA settings?

Hi openSUSE experts!

Tumbleweed x86_64 is working on my ASUS T200TA transformer laptop (tablet), based on Intel Baytrail SoC, 64-bit, 4Gb RAM onboard.

[FONT=courier new]#uname -a
Linux hostname 4.1.6-3-desktop #1 (…) x86_64 GNU/Linux
[/FONT]

Sound device Intel SST is not detected at all, no sound kernel modules are loaded by default, absolutely nothing relevant in dmesg.

Firmware is present, not sure if it is correct one:
/lib/firmware/intel/fw_sst_0f28.bin
/lib/firmware/intel/fw_sst_0f28.bin-48kHz_i2s_master
/lib/firmware/intel/fw_sst_22a8.bin

Any suggestions on where to get compiled kernel modules and what ALSA settings are required?

Some links:
Intel specialists’ technical discussion here.
A brief discussion at alsa-project.org.
https://bugzilla.kernel.org/show_bug.cgi?id=86581
Intel SST driver discussion thread.
This guide is for information only, it’s for T100, and sound hardware is got broken…

If some of you tried something already, please share.
This can be also relevant for other Bay Trail - based devices.

Best regards,
Alexander

Hi Alexander,
I too am also interested in this as i have purchased some Minix Neo Z64’s as MythTV Frontends.
Everything works sweet except the HDMI Audio.

I have no knowledge to add to this, but am commenting so i can keep track of your post.

Cheers,
Leon.

Hi together,
could anyone solve this topic in the meantime?
I have the same problem.
Kind regards
Michael

If the current Tumbleweed kernel does not detect the sound device - then your best best is to obtain help from an alsa developer who also works on the kernel to some extent. Even better, obtain help from one who uses openSUSE.

SuSE-GmbH has at least one sound packager / alsa-developer who does this.

Hence in addition to the kernel bug being raised - I recommend you write a bug report on the openSUSE Tumbleweed (or on Leap-42.1 or Leap-42.2 if you have either of those openSUSE versions installed). This will hopefully get the attention of the openSUSE packager who is your best bet to having this addressed for GNU/Linux and for openSUSE. He aleady contributed a bit to the kernel bug report you referenced.

There is guidance here on how to raise a bug report on openSUSE: https://en.opensuse.org/openSUSE:Submitting_bug_reports

Raise the bug on the kernel. Also run this diagnositic script in a konsole/xterm as a regular user:


/usr/sbin/alsa-info.sh --no-upload

and attach the created file to the bug report.

Include all salient information in the bug report. Do not bother referencing this thread as the openSUSE packager (who can help you) will NOT read a forum thread.

Check the bug report every few days and look for the ‘need info’ flag which indicates you are being asked to do something. When you see that, do the action/answer the question, and then ‘clear’ the ‘need info’ flag. Keep doing such (answer questions/clear the flag / install fixes) until the problem is solved or the openSUSE developer gives you other guidance.

Good luck.

Just to add some extra value and an additional emphasis to this advice.

I am pretty sure oldcpu is talking about T. Iwai and he is one of the main
developers of the alsa project but also on of the susystem maintainers for sound
in linux.

https://www.kernel.org/doc/linux/MAINTAINERS

In addition, he is one of the most active/responsive openSUSE employees on
openSUSE bugzilla.

So yes, go to the openSUSE bugzilla and try to give as much information as
possible, your chances of getting the attention of a person with real expertise
on audio in Linux are very good.
