[alsa-devel] timestamp update when no hw delta
by Henrik Eriksson 30 Oct '17

30 Oct '17

Hi I am looking into commit 3179f62001880e588e229db3006a59ad87b7792a ("ALSA: core: add .get_time_info"), which, if I understand the code correctly, changed the behaviour of timestamps. Before this change, snd_pcm_update_hw_ptr0() just returned if the no_delta_check showed that the hw_ptr had not changed. With this change it will update the timestamps before returning. Was this intended, and if so does anyone have any insights to why? The original behaviour to not update the timestamps when the hw position has not changed seems more correct to me, but I am new to this code. Regards, /henrik

[alsa-devel] [PATCH 0/3] ASoC: wm8741: Varios enhancements
by Sergej Sawazki 30 Oct '17

30 Oct '17

This patch series contains the following 3 patches for the WM8741 codec driver. 1) Adds digital mute callback. 2) Sets oversampling rate mode (OSR), required for sampling rates > 48kHz. 3) Sets MCLK/LRCLK sampling rate ratio (SR), avoids relying on auto-detection.

[alsa-devel] [PATCH linux-next 1/1] ASoC: rsnd: ssiu: reset SSI_MODE register
by jiada_wang＠mentor.com 30 Oct '17

30 Oct '17

From: Jiada Wang <jiada_wang(a)mentor.com> register SSI_MODE is set when SSI works in TDM Extended or TDM (Ex-)Split mode, but it isn't reset after SSI stops. this will cause issue, if SSI starts to work in other modes which requie SSI_MODE to have different value. This patch resets SSI_MODE register in .stop callback, when last stream calls .stop.

[alsa-devel] message size limit
by Jaroslav Kysela 29 Oct '17

29 Oct '17

Hello all, I increased the maximal message size for this alsa-devel list to 200kB (as we discussed with Takashi to allow bigger patches for review). Anyway, if you like to send something big, it's better to upload the data to a public place and provide only URL.
