[alsa-devel] How should SGTL5000 codec driver adapt to dummy regulator change?
by Shawn Guo 03 Dec '13

03 Dec '13

Mark, The sgtl5000_enable_regulators() function in SGTL5000 codec driver makes the decision whether an external VDDD supply is available by checking the return of regulator_bulk_get() call. It used to work because dummy regulator did not play in there, and if regulator_bulk_get() fails, most likely it's only because there is no external VDDD supply. But with commit 4ddfebd (regulator: core: Provide a dummy regulator with full constraints) merged, the regulator_bulk_get() will always succeed. It breaks the driver's assumption. What's your suggestion to the problem? Shawn

[alsa-devel] [PATCH 1/3] ASoC: ux500_pcm: Stop pretending that we support varying address widths
by Lee Jones 03 Dec '13

03 Dec '13

The Slave Config's addr_width attribute is populated by data_width of dma_cfg, which in turn is derived from dma_params' data_size attribute and that comes from the slot_width which is always 16 bits (2 Bytes). We're cutting out the middle man here and just setting the DMA Slave Config directly.

This will not be relevant after you see below answer. > >http://lxr.free-electrons.com/source/sound/core/compress_offload.c >http://lxr.free-electrons.com/source/sound/soc/soc-compress.c Both are compress framework driver files. compress_offload.c file is the one which interacts with userspace by using ioctl's, registers the compressed device with alsa framework(/dev/compress* gets created because of that), calls the corresponding functions such as trigger, pointer update, copy and others when userspace pauses, plays and stops the playback or recording. soc_compress.c file is the file which interacts with compress_offload.c file to create a 'dev' node for compress driver.Basically when you register your compress driver with compress framework,alsa core will come to know that your dai support compress operations and it will create the dev node by using soc_compress.c file.The functions in this file gets called by compress_offload.c functions and who inturn gets called by the userspace. userspace->compress_offload.c->soc_compress.c->your_compress_driver.

[alsa-devel] Bug: plugging in a new sound card causes mixer state of other sound cards to be changed
by Angus McInnes 02 Dec '13

02 Dec '13

Hi, When I plug in my USB sound card, the mixer settings of the internal sound card are changed. I don't want this to happen. I believe the problem is with this commit: http://git.alsa-project.org/?p=alsa-utils.git;a=blobdiff;f=alsactl/90-alsa-… The card number $attr{number} comes from the card* device. Since KERNELS=="card*" was changed to KERNELS!="card*", alsactl restore is run with no card number attribute, so it restores the state of all cards. If I change the != back to ==, alsactl restore is run with a card number and the problem seems to be resolved. (By the way, your bug tracker at https://bugtrack.alsa-project.org/alsa-bug seems to be down.) Regards, Angus McInnes
