[alsa-devel] [PATCH] ALSA: hda - restore the gpio led after resume
by Hui Wang 18 Aug '14

18 Aug '14

On some HP laptops, the mute led is controlled by codec gpio. When some machine resume from s3/s4, the codec gpio data will be cleared to 0 by BIOS: Before suspend: IO[3]: enable=1, dir=1, wake=0, sticky=0, data=1, unsol=0 After resume: IO[3]: enable=1, dir=1, wake=0, sticky=0, data=0, unsol=0 To skip the AFG node to enter S3 can't fix this problem. A workaround is to restore the gpio data when the system resume back from s3/s4. It is safe even on the machines without this problem.

No, that doesn't seem safe. Why not read the data from the control - if we were calling a function which returned the value that'd be much clearer.

No, it's exactly what wm8994_vmid_mode() is there to do already - putting the device into WM8994_VMID_FORCE forces VMID on.

[alsa-devel] [PATCH 0/6] Fix `sparse` warnings
by Lars-Peter Clausen 17 Aug '14

17 Aug '14

This patch series contains a set of fixes for warnings generated by the sparse tool when building the ASoC tree. None of them are critical and the generated code before and after the patch is the same in all cases. The reason for still fixing them is that it makes it easier to recognize new and potentially serious warnings/errors. With this series applied at least on x86 and ARM a allyesconfig on the ASoC tree builds almost without errors or warnings from sparse. The only remaining warnings are the following two: sound/soc/soc-core.c:108:25: warning: Variable length array is used. sound/soc/soc-core.c:109:29: warning: Variable length array is used. These are part of the legacy ASoC IO code that is deprecated and schedulded for removal in the near future so there is not too much motivation for fixing them. - Lars Lars-Peter Clausen (6): ASoC: edma-pcm: Include edma-pcm.h ASoC: odrodix2_max98090: Make non exported symbols static ASoC: rcar: Use && instead of & for boolean expressions ASoC: sh: Fix dma direction type ASoC: samsung idma: Add proper annotation for casting iomem pointers ASoC: ab8500-codec: Drop bank prefix from AB8500_GPIO_DIR4_REG register define sound/soc/codecs/ab8500-codec.c | 11 +++++------ sound/soc/davinci/edma-pcm.c | 2 ++ sound/soc/samsung/idma.c | 4 ++-- sound/soc/samsung/odroidx2_max98090.c | 4 ++-- sound/soc/sh/fsi.c | 7 ++++++- sound/soc/sh/rcar/gen.c | 2 +- 6 files changed, 18 insertions(+), 12 deletions(-) -- 1.8.0

[alsa-devel] [PATCH] ASoC: Use dev_set_name() instead of init_name
by Lars-Peter Clausen 17 Aug '14

init_name is basically a hack and should only be used for statically allocated device structs. For dynamically allocated devices dev_set_name() should be used.

[alsa-devel] the wav jumps on Raspberry, do you think ...
by Carpon frédéric 17 Aug '14

17 Aug '14

Hello, thank for your response and corrections of the topic "minimal_playback.c " from http://equalarea.com/paul/alsa-audio.html There are good tutorials too : http://home.roadrunner.com/~jgglatt/tech/linuxapi.htm http://jan.newmarch.name/LinuxSound/Sampled/Alsa/ On the raspberry, with ArchLinux, the jan.newmarch version and aplay command make the wav jumps for the beginning and sometimes in the middle of the wav music. Do you think it comes from the raspberry’s « bcm2835 ALSA » audio chipset or the arm processor efficiency or other things ? Thank You for your help
