[PATCH 0/2] ASoC: fsl_sai: Fill Tx FIFO to avoid initial underruns
by Sascha Hauer 29 Jun '23

29 Jun '23

This series fixes initial underruns that can occur in the TX queue of the fsl_sai interface when starting playback. These patches are around here for quite some time and have proven useful. Time to upstream them.

[PATCHv2] ALSA: hda/realtek: fix mute/micmute LEDs for HP EliteBook G10
by Huang Rui 29 Jun '23

29 Jun '23

In the commit 3e10f6ca76c4 ("ALSA: hda/realtek: Add quirk for HP EliteBook G10 laptops"), speakers are fixed but mute/micmute LEDs does not lit. Need the ALC287_FIXUP_CS35L41_I2C_2_HP_GPIO_LED to get all mute/micmute LEDs working.

Arturia Minifuse 2 (and probably any other using SplitPCM macro) - lost sample rate range on each in/out (and forced to 48000)

alsa-project/alsa-ucm-conf issue #333 was edited from kmarty: Hi, I have Arturia MiniFuse 2 card allowing playback/capture sample rate in range 44100 - 192000. But using channel name (e.g. `Mic/Line/Inst 1 (L)`, `Main Output L/R`) created by UCM, it offers 48000 only (and in case of playback, it offers S15_LE only). Looks like something is lost when `SplitPCM` macro is used or so (I have absolutely no idea what's going on here).

[PATCH] ALSA: hda/realtek: fix mute/micmute LEDs for HP EliteBook G10
by Huang Rui 29 Jun '23

29 Jun '23

In the commit 3e10f6ca76c4 ("ALSA: hda/realtek: Add quirk for HP EliteBook G10 laptops"), speakers are fixed but mute/micmute LEDs does not lit. Need the ALC287_FIXUP_CS35L41_I2C_2_HP_GPIO_LED to get all mute/micmute LEDs working.

[PATCH] ASoC: hdmi-codec: fix channel info for compressed formats
by Matthias Reichl 29 Jun '23

29 Jun '23

According to CTA 861 the channel/speaker allocation info in the audio infoframe only applies to uncompressed (PCM) audio streams. The channel count info should indicate the number of channels in the transmitted audio, which usually won't match the number of channels used to transmit the compressed bitstream. Some devices (eg some Sony TVs) will refuse to decode compressed audio if these values are not set correctly. To fix this we can simply set the channel count to 0 (which means "refer to stream header") and set the channel/speaker allocation to 0 as well (which would mean stereo FL/FR for PCM, a safe value all sinks will support) when transmitting compressed audio.

MIC Capture Stops due to Playback
by Arjav Parikh 29 Jun '23

29 Jun '23

Hi I am using alsa api's in my C Program to implement two-way talk i.e capturing data from mic and playing sound on speaker received from Cloud. I am using a Microsemi ZL38050 Audio DSP connected to an Ambarella CV25 SOC via I2S/SPI. Randomly I have observed that If I stop and resume receiving data from Cloud to play it on speaker using snd_pcm_writei() then my capture path stops. I do not hear any sound captured from MIC. Can someone help me to debug this issue because when this issue occurs there are no errors reported from Alsa nor do I see anything in dmesg as well. Thanks & Regards, Arjav Parikh
