[PATCH 0/3] ASoC: hdmi-codec: add component name prefix to controls
by Srinivas Kandagatla 06 May '23

06 May '23

While adding audio support to two instances of Display port on x13s, hdmi-codec failed to add controls as two codec instances were trying to add controls with same name. snd-sc8280xp sound: control 3:16:0:IEC958 Playback Mask:0 is already present snd-sc8280xp sound: control 3:16:0:Playback Channel Map:0 is already present hdmi-audio-codec hdmi-audio-codec.4.auto: ASoC: error at snd_soc_pcm_dai_new on i2s-hifi: -16 To fix this issue, I have added a new api snd_pcm_add_chmap_ctls_with_prefix() to allow to pass asoc component name prefix, which should provide a unique control names. We can also make snd_pcm_add_chmap_ctls() take prefix argument to do the same this. Srinivas Kandagatla (3): ALSA: pcm: add snd_pcm_add_chmap_ctls_with_prefix ASoC: hdmi-codec: use snd_pcm_add_chmap_ctls_with_prefix to add controls ASoC: hdmi-codec: use snd_soc_cnew to add controls include/sound/pcm.h | 7 +++++++ sound/core/pcm_lib.c | 30 ++++++++++++++++++++++++++++-- sound/soc/codecs/hdmi-codec.c | 10 ++++++---- 3 files changed, 41 insertions(+), 6 deletions(-) -- 2.21.0

[PATCH alsa-lib 0/4] pcm: hw: implement explicit silencing for snd_pcm_drain
by Jaroslav Kysela 05 May '23

05 May '23

This is a complete API solution for the filling of the silence samples for the drain operation. The default bahaviour is to aligns the valid samples to one period with extra silence samples for next 1/10th of second. Introduce SNDRV_PCM_INFO_PERFECT_DRAIN and SNDRV_PCM_HW_PARAMS_NO_DRAIN_SILENCE flags to fully control the filling of the silence samples in the snd_pcm_drain call. Those flags do the bidirectional setup for this operation, so the silencing may be implemented eventually in the kernel space when there's a demand in future. Also, some applications may not require to silence the samples beyond the tail of the ring buffer at all. There is also a new pcm_hw plugin configuration field allowing the overwrite of the default (auto) behaviour.

[PATCH 1/7] ALSA: pcm: Revert "ALSA: pcm: rewrite snd_pcm_playback_silence()"

From: Jaroslav Kysela <perex(a)perex.cz> This reverts commit 9f656705c5faa18afb26d922cfc64f9fd103c38d. There was a regression (in the top-up mode). Unfortunately, the patch provided from the author of this commit is not easy to review. Keep the updated and new comments in headers. Also add a new comment that documents the missed API constraint which led to the regression.

[PATCH v2 1/7] ALSA: pcm: Revert "ALSA: pcm: rewrite snd_pcm_playback_silence()"
by Oswald Buddenhagen 05 May '23

05 May '23

From: Jaroslav Kysela <perex(a)perex.cz> This reverts commit 9f656705c5faa18afb26d922cfc64f9fd103c38d. There was a regression (in the top-up mode). Unfortunately, the patch provided from the author of this commit is not easy to review. Keep the updated and new comments in headers. Also add a new comment that documents the missed API constraint which led to the regression.
