If the sound card does not support multi-streaming , the mic is one of the choice in the "Capture Source" controls If your application can find "Input Source" in your sound card , this mean that your sound card support multi-streaming capture i.e. there will be more than one "Input Source" controls

[alsa-devel] [patch] ASoC: soc: snprintf() doesn't return negative
by Dan Carpenter 12 Oct '10

12 Oct '10

In user space snprintf() returns negative on errors but the kernel version only returns positives. It could potentially return sizes larger than the size of the buffer so we should check for that.

Thanks for the prompt reply, it fixed the mic problem. Can you say anything about the headphone problem? Plugging -in/-out headphones doesn't have any effect. Regards.

We know that the only possible error that is currently returned is -EINTR though, so we could do a similar trick and define another #define __cond_mutex(x, c) ((!c) ? ({ __acquire(x); 0; }) : -EINTR) My fear was that this would impact code generation. Arnd

[alsa-devel] [PATCH 0/10] Add S/PDIF common driver for Samsung SoCs
by Seungwhan Youn 12 Oct '10

12 Oct '10

Hi, This patch-set is for new S/PDIF common driver that supports S/PDIF PCM audio on S5PC100, S5PC110 and S5PV210. This patch-set is based on two different branches that :- o ASoC patches are based on Mark Brown's git branch 'for-next' (commit id - 135e44aaa47c22b66c8d2acb54da1106a6c17598) o ARM patches are based on Kukjin Kim's git branch 'for-next' (commit id - a9d09cac7485062c599ee8f341bb0c5ccc2cc9d6) Based on these patches S/PDIF driver supports followings :- o Playback supports {32, 44.1, 48 and 96}kHz sampling rates. o Playback supports 16-bit Little-endian PCM format. This patch-set contains followings :- o To Kukjin Kim and Ben Dooks, - [PATCH 1/10] ARM: S5PC100: Add S/PDIF platform device - [PATCH 2/10] ARM: S5PC100: Modify SCLK_AUDIO{0,1,2} clock as sysclks - [PATCH 3/10] ARM: S5PC100: Add SCLK_SPDIF clock - [PATCH 4/10] ARM: S5PV210: Add S/PDIF platform device - [PATCH 5/10] ARM: S5PV210: Add SCLK_SPDIF clock - [PATCH 6/10] ARM: S5PV210: Add audio clocks as sysclk - [PATCH 7/10] ARM: S5PV210: Fix wrong EPLL rate getting on setup clocks - [PATCH 8/10] ARM: S5PV210: Add EPLL clock operations o To Jassi Brar, Mark Brown and Liam Girdwood, - [PATCH 9/10] ASoC: SAMSUNG: Add S/PDIF CPU driver - [PATCH 10/10] ASoC: SAMSUNG: Add Machine driver for S/PDIF PCM audio Best Regards, Claude(Seungwhan Youn)
