[alsa-devel] [PATCH v5] ASoC: sgtl5000: Fix the cache handling
by Fabio Estevam 27 May '14

27 May '14

Since commit e5d80e82e32e (ASoC: sgtl5000: Convert to use regmap directly) a kernel oops is observed after a suspend/resume sequence. The kernel oops happens inside sgtl5000_restore_regs() as codec->reg_cache is no longer a valid pointer. Add the remaining register entries into sgtl5000_reg_defaults[] and remove sgtl5000_restore_regs() completely, which allows suspend/resume to work fine and make the code simpler. Tested on a im53-qsb board.

[alsa-devel] [PATCH] ASoC: jack: Clarify GPIO descriptor lookup in struct snd_soc_jack_gpio doc
by Jarkko Nikula 27 May '14

27 May '14

Clarify struct snd_soc_jack_gpio documentation for the idx and name fields. Because name is passed as connection ID to gpiod_get_index() when using GPIO descriptor defined jack pins it is not only used as a label in debugfs but also as function name lookup in systems that support functions names for GPIOs. Clarify also idx since the index is within the function of the GPIO consumer device and not within the device itself only.

[alsa-devel] [PATCH v4 00/17] ASoC: fsl-ssi: Driver cleanup
by Markus Pargmann 27 May '14

27 May '14

Hi, This series is a cleanup of the fsl-ssi driver. v4 includes the changes I made to fix the baudclock handling. I moved the baudclock enable/disable function calls into hw_params()/hw_free(). To avoid inconsistent reference counters for the baudclock I use a variable baudclk_streams which describes the active streams to be able to decide if we have to enable/disable the clock and set the rate. I currently don't have a board to test i2s-master, maybe I am able to test it next week. The new patch which includes these changes is "ASoC: fsl-ssi: Fix baudclock handling". Best regards, Markus Changes in v4: - New patch to fix baudclock handling (enable/disable/set_rate) Changes in v3: - Some new patches to improve/fix i2s master mode by Sascha - baudclock is enabled/disabled in startup/shutdown now - bitclock setup moved to a seperate function (not set_dai_sysclk) - Regmap config changed to NATIVE now.

[alsa-devel] aplay: main:722: audio open error: No such file or directory

Hello! Apologies if this is not the right place to report this. I tried to use the bug tracker at <https://bugtrack.alsa-project.org/alsa-bug>, but both times I went to it (a couple of weeks ago and again today) it was offline. Also, I am not subscribed to the list, so please include me in replies (or tell me if this is not acceptable and I will subscribe). I can't play audio on non-default devices. Running aplay with no options, or with -D default, works fine. Running aplay with -D hdmi does not work, failing with this message: aplay: main:722: audio open error: No such file or directory Running it in strace, I see that the last interesting thing it does before printing that message is it tries to open /dev/snd/pcmC0D3p, which does not exist; it should probably be addressing pcmC1D3p instead.
