[alsa-devel] [PATCH 0/3] ALSA: hdac: stream fixes
by Vinod Koul 04 Aug '15

04 Aug '15

Hi Takashi, I had few off fixes on hdac piled up so time to send them out. First one is a fix for stream assignment for decoupled mode used in SKL driver. Second one is static checker fix reported by Dan Carpenter Last is a potential issue which our team reported so a WA for that. The command DMAs do not finish instantaneously, so we should per spec wait till DMA finishes Jeeja KP (2): ALSA: HDA: Fix stream assignment for host in decoupled mode ALSA: HDA: Dont check return for snd_hdac_chip_readl Vinod Koul (1): ALSA: HDA: wait for RIRB, CORB DMA to finish sound/hda/ext/hdac_ext_controller.c | 6 ------ sound/hda/ext/hdac_ext_stream.c | 2 +- sound/hda/hdac_controller.c | 14 ++++++++++++++ 3 files changed, 15 insertions(+), 7 deletions(-) -- 1.9.1

[alsa-devel] Question about Component and Card
by Kuninori Morimoto 04 Aug '15

04 Aug '15

Hi Lars Cc Mark I noticed my sound card (which is not upstreamed) can't probe in next branch. I think it is because this patch 1b7c12316982f74a5b8e7704c24cf5524d0723a3 (ASoC: Prevent components from being bound to multiple cards) In my case, my sound device (= CPU) has some DAIs, and these are connected to some codecs. It is shown as below. And I would like to use these as 2 sound cards. ex) aplay -D hw:0 xxx aplay -D hw:1 xxx But, 2nd sound card can't probe because of above patch now. (component->card indicates 1st card) It can be probeed if I used DPCM card (= 1 CPU + 2 Codec), but... But, is my understanding wrong ? codec0: codec@0 { xxx }; codec1: codec@1 { xxx }; sound: sound@0xxxxxx { #sound-dai-cells = <1>; rcar_sound,dai { dai0 { xxxx }; dai1 { xxxx }; }; }; card@0 { compatible = "simple-audio-card"; simple-audio-card,cpu { sound-dai = <&sound 0>; }; simple-audio-card,codec { sound-dai = <&codec0>; }; }; card@1 { compatible = "simple-audio-card"; simple-audio-card,cpu { sound-dai = <&sound 1>; }; simple-audio-card,codec { sound-dai = <&codec1>; }; };

[alsa-devel] Alsa issue faced in port audio
by Srinivasan S 03 Aug '15

03 Aug '15

Dear ALSA Community, Am running port-audio(pjproject-2.4 & 2.3) on linux kernel version 3.14 & alsa-lib verison 1.0.27, but some how portaudio ALSA handles under/overrun in blocking read/write: it is never reported back to the application: handleXrun tries to recover, usually this works and leaves the stream in STATE_PREPARED. The xrun flag is set but neither the portaudio ALSA read nor the write methods look at this when they are in the read/write while loop. In case of playback this causes bad "framesAvail" values. The read funtion enters an endless loop. In port audio in writeframes for each time for read samples playback/capture poll will happen in this poll(snd_poll_descriptor_revents) we will get read/write event from device in the success case, when Xrun occurs the poll always returns 0 or NULL, which indicates A value of 0 indicates that the call timed out and no file descriptors were ready.But we traced the source code file descriptor is available & not corrupted Could you please let us know how this can be fixed in ALSA Kindly do the needful as early as possible Srinivasan S
