[alsa-devel] [PATCH v13 6/7] ASoC: amd: Added ACP3x system resume and runtime pm
by Ravulapati Vishnu vardhan rao 02 Dec '19

02 Dec '19

When system wide suspend happens, ACP will be powered off and when system resumes,for audio usecase to continue,all the runtime configuration data needs to be programmed again. Added resume pm call back to ACP pm ops and also added runtime PM operations for ACP3x PCM platform device. Device will enter into D3 state when there is no activity on audio I2S lines.

[alsa-devel] [PATCH v13 2/7] ASoC: amd: Refactoring of DAI from DMA driver
by Ravulapati Vishnu vardhan rao 02 Dec '19

02 Dec '19

ASoC: PCM DMA driver should only have dma ops. So Removed all DAI related functionality.Refactoring the PCM DMA diver code.Added new file containing only DAI ops.

[alsa-devel] regression: aplay -L missing pulse in 1.2.1
by GitHub issues - opened 30 Nov '19

30 Nov '19

alsa-project/alsa-plugins issue #3 was opened from higuita: Before 1.2, `aplay -L` showed a pulse pcm. After the commit https://github.com/alsa-project/alsa-plugins/commit/b0f9c353c7cc9cffb77e7a7… pulse is missing from the pcm list. This may break some apps, war thunder (used fmod) game stopped seeing pulse and only tried to use alsa directly if i comment out the below line in /usr/share/alsa/alsa.conf.d/50-pulseaudio.conf `@args [ DEVICE ]` `aplay -L` show again the pulse pcm another workaround is to add this to the `/etc/asound.conf` : ``` pcm.!pulse { type pulse hint { show on description "PulseAudio Sound Server" } } ``` Issue URL : https://github.com/alsa-project/alsa-plugins/issues/3 Repository URL: https://github.com/alsa-project/alsa-plugins
