[alsa-devel] Regression Intel Corporation Haswell-ULT HD Audio Controller
by Delcypher 05 May '14

05 May '14

Hi, I was told to report my bug here because the ALSA bug tracker is no longer active. I'm having an issue with " Intel Corporation Haswell-ULT HD Audio Controller" card which is inside the Dell XPS13 9333 developer edition [1]. I've tried two different distributions * Arch Linux (kernel 3.14) Output of alsa-utlils-alsa-info.sh [2] * Ubuntu 14.04 LTS (kernel 3.13) Output of alsa-utlils-alsa-info.sh [3] The card behaves correctly under Ubuntu but under Arch Linux I've observed the following issues. - The microphone does not work correctly. In alsamixer I select "Internal Mic" as my capture device but when I do $ arecord -d 5 test.wav $ aplay test.wav test.wav contains silence. I've also tried enabling/disabling "CAPTURE" on the Capture channel at the same time - I don't really understand why this channel is here (seems a little bizarre) but enabling/disabling "CAPTURE" on this channel doesn't seem to make any difference anyway. Under Ubuntu the "arecord... aplay" command works correctly. - There probably isn't a way to reproduce this but when I first installed Arch Linux the sound card was put in a state where the headphone jack would not work at all. Sound would continue playing out of the speakers when the headphone jack was inserted and no sound would come out of the headphones. I did notice that if the headphone jack was only partially inserted I would get some sound sent to one of the headphones. My intuition is that the card is probably being incorrectly initialised because if you take a look at the output of alsa-utils-alsa-info.sh and diff them. Two very big differences I noticed were that - The card name (from lscpi) is "Intel Corporation Haswell-ULT HD Audio Controller" under Ubuntu but under Arch Linux it is "Intel Corporation Device 0a0c" - The card codec is "Realtek ALC668" under Ubuntu but is "Realtek ALC3661" under Arch Linux. One interesting I did notice is that under Arch Linux it is possible to use the microphone from the Audacity program by selecting "HDA Intel PCH: ALC3661Analog (hw0:0) Internal mic:0" as the input (this is not the default). Unfortunately I know of no way to make other applications use this. Any thoughts on how to fix this?

[alsa-devel] ALC1150 can't playback SND_PCM_FORMAT_FLOAT without dmix
by Madura Anushanga 04 May '14

04 May '14

Hi, MSI z87-GD65 GAMING motherboard's ALC1150 plays SND_PCM_FORMAT_FLOAT with noise[1] other non float formats work well. As soon as I changed /etc/asound.conf from pcm.!default{ type hw card 1 } to pcm.dmixed { type asym playback.pcm { type dmix ipc_key 5678293 ipc_perm 0660 ipc_gid audio slave { channels 2 # make 6 or 5.1 channel pcm { format S16_LE # S32_LE rate 48000 # can also be 44100 type hw card 1 # your card device 0 # your device subdevice 0 #important? } period_size 1024 buffer_size 8192 } bindings { 0 0 1 1 # Uncomment below if using 6 channel # 2 2 # 3 3 # 4 4 # 5 5 } } capture.pcm "hw:0" } pcm.!default { type plug slave.pcm "dmixed" } SND_PCM_FORMAT_FLOAT plays without a problem. 1. https://github.com/manushanga/vrok/blob/master/outs/alsa.cpp - Madura A.

[alsa-devel] [PATCH 13/15] ASoC: SND_S3C_DMA_LEGACY needs S3C24XX_DMA
by Xia Kaixu 02 May '14

02 May '14

From: Arnd Bergmann <arnd(a)arndb.de> SND_S3C_DMA_LEGACY can only be set on S3C24xx, which does not (yet) support the dmaengine framework, so samsung_dma_get_ops() fails to link if S3C24XX_DMA is disabled: sound/built-in.o: In function `dma_hw_params': :(.text+0x7f310): undefined reference to `s3c_dma_get_ops' sound/built-in.o: In function `s3c_ac97_trigger': :(.text+0x7f7f0): undefined reference to `s3c_dma_get_ops' sound/built-in.o: In function `s3c_ac97_mic_trigger': :(.text+0x7f884): undefined reference to `s3c_dma_get_ops' sound/built-in.o: In function `s3c2412_i2s_trigger': :(.text+0x80944): undefined reference to `s3c2410_dma_ctrl' This makes sure S3C24XX_DMA is always enabled when we need it, just like we do it for the same dependency in SND_S3C24XX_I2S, which has the same problem. Selecting "S3C2410_DMA" as we did before does not actually have the intended effect, since that one is only used on the s3c2410 and s3c2442 SoCs of the s3c24xx family, but not the others, so we can remove this from Kconfig.
