[alsa-devel] Using 2 codecs together in a system
by Appalayagari Sreedhar 24 Nov '11

24 Nov '11

Hi, We have interfaced DM368 processor with one external codec and also to the internal codec. I am working on voip phone. we have interfaced the Internal codec to Cradle. i.e., Cradle Mic and Cradle Spk to the Internal codec and External codec.to the Handsfree mode. Is it possible to switch dynamically between the codecs (Internal and External) when user chooses Cradle and after sometime Handsfree vice versa. If so could you please put some light on this topic how this can be implemented. what changes i need to do to my code to make this work. if any reference code is available please suggest. Thank you in advance, Sreedhar

[alsa-devel] [PATCH v7 0/3] ARM: mxs: add recording support for saif
by Dong Aisheng 24 Nov '11

24 Nov '11

Changes since v6: * fix a typo suggested by Shawn * add tag from Marek Vasut Changes since v5: Only one change is that: * remove the unneccesary parenthesis for [PATCH 1/3] suggested by Marek Vasut. Changes since v4: * use new added master_id and master_mode in platform_data. The new changes depend on another patch: 0001-ASoC-mxs-saif-remove-function-in-platform_data.patch Changes since v3: * remove unneeded locking according to Sascha. The patches are based on imx-features branch since commit: ca4e419c2. Changes since v2: * separate clkmux code into another patch according to Uwe * add lock according to Wolfram * Other minus fixes suggested by Uwe and Wolfram. * remove Wolfram's fix saif clock setting patch which is in v2 series since Wolfram will reform the clock code and send it out himself. For test purpose, user still needs that patch. People can get it from v2 series. The patch is: [PATCH v2 3/3] arm: mxs: disable clock-gates when setting saif-clocks The patches are based on imx-features branch since commit: f4f01e31835f. Changes since v1: The main changes are move mach-specific code(clkmux in DIGCTL) from saif driver to mach-specific layer based on Wolfram's suggestion. Note that the last patch is a RFC patch and sent out for testing since without that patch the saif may not work.

Hi, if this function has been used to tell the sound core that a device is in a powersave mode, will the soundcore allow user space to open it? Regards Oliver
