Public bug reported:
[SRU Justifications]
========== alsa-ucm-conf ==========
[Impact]
Audio output doesn't work on Dell Tarako platforms with Cirrus CS42L43
codec
[Fix]
This requires following conf file in alsa-ucm-conf package:
- /usr/share/alsa/ucm2/sof-soundwire/cs42l43-spk.conf
[Test Case]
1. Boot up the machine of Dell Bolan platform with CS42L43 codec
2. Verify the existence of /usr/share/alsa/ucm2/sof-soundwire/cs42l43-spk.conf
3. Verify with checking the output of `aplay -l` command with valid sof output
device. Should never be dummy output.
[Where problems could occur]
It only affects the Dell Tarako platforms with the new CS42L43 codec w/o other
soundwire devices. Should be low low risk of regression
========== firmware-sof ==========
[Fix]
This requires following tplg file in firmware-sof
- sof-lnl-cs42l43-l0.tplg
upstream firmware-sof 2.11 will have this tplg file included.
[Test Case]
1. Boot up the machine of Dell Tarako platform with cs42l43 internal speakers
2. Verify with checking the output of `aplay -l` command with valid sof output
device. Should never be dummy output.
[Other Info]
The name of sof-lnl-cs42l43-l0.tplg includes useful information which indicates
that the topology is for for the cs42l43 codec connected to soundwire bus 0 w/o
other soundwire devices connected on 1/2/3. It only affects the machines which
has exactly the same soundwire configuration. The upstream commit of a newer
version usually include the topology files for the new platforms or missing
configuration on old platforms. It would be better to catch up with upstream to
have these configuration which can support more configurations we could be
missing in the future. The the addtional
0002-Add-SOF-v2.11.1-signed-Intel-binaries-for-MTL-LNL-AR.patch, it's required
for each new Intel Platform and signed by Intel. In the case, the tplg file
specify the `lnl`, a signed LunarLake DSP FW will be necessary. It would be
better to have the Intel signed DSP FW up-to-date.
[Where problems could occur]
Although there're lots of new tplg files added, but they are mostly for missing
configuration on old platforms or newly added for next-gen Intel platform. And
they are specified for particular soundwire configurations which can hardly
affect the existing machines. The risk for regression may come from
sof-hda-generic-xxx.tplg which is for generic HDA. I'll consider it as low risk.
