[alsa-devel] [PATCH] ASoC: core: Mark regmap CODEC register maps as dirty when suspending
by Mark Brown 12 Sep '12

12 Sep '12

The core has for a long time had support for marking the register maps of devices dirty when suspending so that they are resynced on resume. Also implement this feature for CODECs using regmap.

[alsa-devel] ASOC: dapm event errors not reported
by Pierre Peiffer 12 Sep '12

12 Sep '12

Hi, I have observed that in dapm, most of the errors of widget event calls are reported in kernel log but not returned to the caller. This leads in some cases to a situation where the error is not reported to the userspace caller, letting it continue, even if it can't and following calls from userspace will fail as well. Is there a reason for this ? Thanks & BR -- Pierre

[alsa-devel] Amixer: suppressing errors when called from stdin
by Henrik Fasth 12 Sep '12

12 Sep '12

Hi, We have some problems with amixer always returning 0 when called from stdin (exec_stdin). The global variable ignore_error is always set to 1 in function exec_stdin which leads to sset and cset always returning 0 even if an error occured. Are there any specific reasons for suppressing error messages and error return values like this? Br Henrik

[alsa-devel] [PATCH V3] ASoC: Davinci: machine: Add device tree binding
by Hebbar, Gururaja 12 Sep '12

12 Sep '12

Device tree support for Davinci Machine driver When the board boots with device tree, the driver will receive card, codec, dai interface details (like the card name, DAPM routing map, phandle for the audio components described in the dts file, codec mclk speed). The card will be set up based on this information. Since the routing is provided via DT we can mark the card fully routed so core can take care of disconnecting the unused pins. When here, code indentation and comment style is also fixed Signed-off-by: Hebbar, Gururaja <gururaja.hebbar(a)ti.com> --- Changes from V1: - Change DT parameter from "ti,codec-clock" to "ti,codec-clock-rate" - add more explanation to DT parameters Changes from V2: - Update Documentation details - Remove irrelevant commit message :000000 100644 0000000... b248014...

[alsa-devel] [PATCH] ALSA: hda_intel: add position_fix quirk for Asus K53E
by Catalin Iacob 12 Sep '12

12 Sep '12

Commit c20c5a841cbe47f5b7812b57bd25397497e5fbc0 changed some chipsets to default to POS_FIX_COMBO so they now use POS_FIX_LPIB instead of POS_FIX_POSBUF. Since then I've been getting artifacts on playback, including repeated sounds on my Asus laptop. My hardware is Cougar Point which the commit log of c20c5a841cbe47f5b7812b57bd25397497e5fbc0 mentions as tested so POS_FIX_COMBO probably works in general but apparently it doesn't on Asus K53E therefore the need for the quirk.
