[alsa-devel] [PATCH v2] ALSA : hda - not use assigned converters for all unused pins
by mengdong.lin＠intel.com 26 Sep '13

26 Sep '13

From: Mengdong Lin <mengdong.lin(a)intel.com> BIOS can mark a pin as "no physical connection" if the port is used by an integrated display which is not audio capable. And audio driver will overlook such pins. On Haswell, such a disconneted pin will keep muted and connected to the 1st converter by default. But if the 1st convertor is assigned to a connected pin for audio streaming. The muted disconnected pin can make the connected pin no sound output. So this patch avoids using assigned converters for all unused pins for Haswell, including the disconected pins.

[alsa-devel] IMX WM8740 I2S support
by stéphane cerveau 25 Sep '13

25 Sep '13

Dear all, I'm currently working on supporting WM8740 device software configured with imx6q system. For now my driver seems to be configured correctly. The playback is launched but i get: ALSA sound/core/pcm_lib.c:1822 playback write error (DMA or IRQ trouble? write error: Input/output error The imx ssi is not sending me any data on I2S bus( nothing can be seen on the oscillo). I would like to know how do I have to configure my master clock in order to launch the I2S. My master clock is for now 24MHz. Sorry to be confused a bit but i'm quite newbie with this device. Best regards. Stéphane
