[PATCH] ALSA: pcmtest: Move buffer iterator initialization to prepare callback
by Ivan Orlov 04 Aug '23

04 Aug '23

Trigger callback is not the best place for buffer iterator initialization, so move it out to the prepare callback, where it have to be. Minor enhancement: remove redundant definitions and blank line.

It's separate issue, but yes - why requiring them? I wrote about missing constraints for your clocks in the bindings. Best regards, Krzysztof

[RFC] aplay: Add option for specifying subformat
by GitHub pull_request - opened 04 Aug '23

alsa-project/alsa-utils pull request #228 was opened from crojewsk-intel: Make subformat first-class citizen by allowing users to specify it just like it is the case for the format. Default to SND_PCM_SUBFORMAT_STD so they are no surprises.

alsa-project/alsa-lib pull request #342 was opened from crojewsk-intel: Improve granularity of format selection for S32/U32 formats by adding masks representing 20 and 24 most significant bits. As a preparation step introduce `snd_pcm_subformat_value()` for easy name-to-subformat conversions. While at it, fix few warnings that pop up in subformat-related code during compilation.

[PATCH v2 RESEND*3] ASoC: fsl MPC52xx drivers require PPC_BESTCOMM
by Randy Dunlap 03 Aug '23

03 Aug '23

Both SND_MPC52xx_SOC_PCM030 and SND_MPC52xx_SOC_EFIKA select SND_SOC_MPC5200_AC97. The latter symbol depends on PPC_BESTCOMM, so the 2 former symbols should also depend on PPC_BESTCOMM since "select" does not follow any dependency chains.
