Comments/Problems:

No analogue sound on Tablet from Broadwell-U from intel smart sound chipset -
hw works on Buster but breaks on Bullseye
Card0 on Buster no longer detected on Bullseye

Tried installing Intel SOF drivers/firmware to no effect, forcing snd_hda_intel
via modprobe conf doesn't work either
Broadwell-U works eith with HDA or SOF drivers theoretically.
There is record of a kernel compilation flag to enable SOF functionality
SND_SOC_SOF_BROADWELL_SUPPORT=Y breaking legacy and snd_hda_intel too.

Control: reassign -1 src:linux
Control: retitle -1 Missing support for Haswell/Broadwell platforms with I2S codec present

Due to various bugs, Intel has rewritten the audio driver for Haswell/Broadwell
in Linux 5.10.
The bad news is that our kernel configuration does not seem to provide the
necessary bits to enable support for the Intel Audio DSP on Haswell U/Y and
Broadwell U.
I'm willing to provide a patch to fix this but the release of Bullseye is
approaching really fast so we might have to wait for the first point release.

We do not support SOF on Broadwell. This is even not recommended by upstream due
to some limitations related to DMA and suspend-resume so installing
firmware-sof-signed is of no use in your case.

Do you have firmware-sof-signed installed? It may be needed on your system.

Hi,

Reopened the bug for now (at least until the above question is
clarified).

Regards,
Salvatore

[Vincent Blut]

Hi Salvatore,

Dekks replied to me privately. Those SOF audio firmware aren't going to help in
this case since we don't provide support for SOF on Broadwell based platforms.
I already mentioned this in [1] but I had totally forgotten that.

Dekks, out of curiosity, could you please post the output of 'pacmd list-sinks'?

From a quick look, alsa-info reports that you're running both PipeWire and
PulseAudio sound servers. While it may not be the root cause of your issue,
if you want to stick with the former, please disable the latter:
$ sudo systemctl --user disable --now pulseaudio.service pulseaudio.socket

Note though that using PipeWire as a substitute to PulseAudio/JACK/ALSA in
Debian 11 is considered experimental.

Vincent

Err: the above command should not be run with sudo.

Hi Vincent

I'll kill the pipewire server, i would uninstall the packages but they are hard deps for gnome now.

Is the fw file catpt is trying to load the correct one? Is there new fw files that come with catpt that have been forgotten?

Is there a listiing for the error codes -110 and -2, are they missing files or read permission issues?

Regards.....

[Dekks Herton]

problem resolved, i think.

new sof firmware update came out, not sure its arrival was more than a coincidence

1 - disabling all intel vitrualisation options in the helix bios was enough to allow the fw to load thus  pavucontrol was now seeing input bars moving but no sound output.

2 - ran alsactl -U init after i noticed ucm errors when running alsactl init.

3 - aplay -l now sees all 3 cards when docked and 2 when tablet only.

4 - alsamixer still showed the correct hw but a lot of outputs were muted, by enabling and disabling them all in sequence enabling the front dac enabled sount from the rt256 card and headphone socket.

I'm doing basic checks like detaching and reattaching to see if that affects the sound, so far ok Only noticeable thing is the fw gets reloaded 3 or 4 times a session, but doesn't seem to affect anything . If i have not commented more  in a week feel free to close the bug.

Hi,

One week has passed, as per your request I'm closing this bug report. Feel free
to reopen it if the issue recurs.
