Wolfson wm8731 audio codec in Pi 5 does not work (works with Pi 4!) about linux

[rafael2k]

Just adding - that in this state the wm8731 is totally unusable.

[rafael2k]

Also, the schematics of the radio (includes the wiring between the wm8731 and the Pi), just in case: https://github.com/afarhan/sbitx/blob/main/sbitx_v3_production.pdf

[rafael2k]

Also tested with kernel 6.6.8-v8+, same issue.

[pelwell]

That soundcard driver is using unusual bclk_ratio values, apparently aiming to maintain a constant bclk frequency of 12MHz rather than scaling with the sample size and frequency. But reading the dwc_i2s bclk_ratio handling again and comparing it to that of other I2S blocks shows that:

1. the value would likely have been ignored, and
2. it should only be a factor in clock producer mode.

#5819 should address both of those, and may solve the problem with your soundcard. Wait about 45 minutes for the build/checks to complete, then run sudo rpi-update pulls/5819 to install a trial kernel (usualy caveats apply).

[pelwell]

The build is ready now, if you'd like to give it a try.

[rafael2k]

OK, testing now. Thanks @pelwell !!

[rafael2k]

Roger that! Loud and clear!

All good, sound card working again. Thanks @pelwell !

[pelwell]

Thanks. I should probably do some basic testing of a few other soundcards before merging...

[rafael2k]

Cool! Do you close this one when you do these checks?
: )

[pelwell]

Will do.

[pelwell]

Now tested and merged.

[rafael2k]

Should I open this again?
For me, 6.1.74 broke again the wm8731 "snd_soc_audioinjector_pi_soundcard", but now in the Pi 4. 6.1.73 was working fine. I'm getting same kind of errors:
