[alsa-devel] HD audio problem
by Russ Whitaker 20 Dec '13

20 Dec '13

Hi Bought a new mini-itx mb: ECS KBN-I On board sound chip: VT1705CF Installed kernel linux-3.10.24 Otherwise distro is Slackware64 14.1 mplayer plays .mp3 files just fine. No sound from video clips that use Adobe flashplayer, and I get this error message: ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave I think the problem is: card0 and card1 are interchanged as card0 is listed as the HDMI video output. How to fixit, please. Thank you, Russ

[alsa-devel] [PATCH] ASoC: imx-spdif: Use module_init() to handle platform_device_register()
by Nicolin Chen 20 Dec '13

20 Dec '13

This is a quick fix for the below two issues when building spdif as modules. 1) When modprobing modules in order: snd-soc-fsl-spdif -> snd-soc-imx-spdif -> snd-soc-spdif-tx/rx, we will fail to create imx-spdif card and dai link unless we rmmod snd-soc-imx-spdif and modprobe it again due to inappropriate condition of platform_driver_unregister() in probe(). 2) After "imx-spdif sound-spdif.17: dit-hifi <-> 2004000.spdif mapping ok", doing rmmod the imx-spdif would cause kernel Oops: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 1301 at /home/rmk/git/linux-rmk/fs/sysfs/dir.c:915

no directory". But the root cause seems to be beyond the imx-spdif driver level, which might be related to the disordered resource releasing of the whole link. Thus this patch can provide a quick fix, if acceptable, to these two bugs so that the driver can finely work when being built as modules. And it's also safe enough to avoid duplicate regisitering/unregistering since we don't handle them in the probe() and remove() any more. At the meantime, we can trace the root cause of the Oops without pressure.

[alsa-devel] [PATCHv3 0/8] ALSA: Add SAI driver and enable SGT15000 codec
by Xiubo Li 20 Dec '13

20 Dec '13

This patch series is mostly Freescale's SAI SoC Digital Audio Interface driver implementation. And the implementation is only compatible with device tree definition. This patch series is based on linux-next and has been tested on Vybrid VF610 Tower board using device tree. Changed in v3: - Add big-endian mode support. - Revise some commit comments, coding styles,etc. - Keep header files ordered by alphabet,etc. - Add MODULE_ALIAS("platform:fsl-sai") for SAI driver. - Rename the files to be in a same pattern with the existed ones. - Remove some not useful functions or code. - Only enable the clock while the device is in active use. - Revise one error message according to Bill. Changed in v2: - Use default settings for the generic dmaengine PCM driver. - Separate receive and transmit setting in most functions, but some couldn't for the HW limitation. - Drop some not reduntant code. - Use devm_snd_soc_register_component() instead of snd_soc_register_component(). - Use devm_snd_soc_register_card() instead of devm_snd_soc_register_card(). - Adjust the code sentences sequence. - Make the namespacing consistent. - Rename CONFIG_SND_SOC_FSL_SGTL5000 to CONFIG_SND_SOC_FSL_SGTL5000_VF610. - Drop some meaningless lines. - Rename the binding document file. Added in v1: - Add SAI SoC Digital Audio Interface driver. - Add Freescale SAI ALSA SoC Digital Audio Interface node for VF610. - Enables SAI ALSA SoC DAI device for Vybrid VF610 TOWER board. - Add device tree bindings for Freescale SAI. - Revise the bugs about the sgt15000 codec. - Add SGT15000 based audio machine driver. - Enable SGT15000 codec based audio driver node for VF610. - Add device tree bindings for Freescale VF610 sound.

[alsa-devel] [PATCH 0/5] ASoC/MFD: twl6040: Remove codec driver local reg cache
by Peter Ujfalusi 19 Dec '13

19 Dec '13

Hi Mark, It was not straight forward task to remove the local reg cache from the twl6040 codec driver. I also needed to change the MFD part so it will take over the caching of registers via regmap. So far I have the following patches working on top of mainline kernel. Is this close enough of what you had in mind when asked me to look at this? twl4030 codec is going to be a bit more complicated AFAIK but it will come eventually. Regards, Peter --- Peter Ujfalusi (5): ASoC: twl6040: Rename twl6040_is_path_unmuted -> twl6040_can_write_to_chip ASoC: twl6040: Custom caching for sensitive DL1/2 path registers MFD: twl6040: reg_defaults support for regmap ASoC: twl6040: Remove register restore functionality ASoC: twl6040: Remove self managed local reg_cache support drivers/mfd/twl6040.c | 92 +++++++++++++++++- sound/soc/codecs/twl6040.c | 227 +++++++++++++-------------------------------- 2 files changed, 155 insertions(+), 164 deletions(-) -- 1.8.4.2
