[alsa-devel] ALC262 models
by Jure Koren 01 Sep '09

01 Sep '09

Hi! I've received a Vaio P netbook recently, which contains an ALC262 of an unknown model. Playback generally works out of the box, but I haven't yet managed to raise the capture level for the internal microphone (though it's easy to rev up the passthrough channel which makes a nice white noise without any feedback). What I'd like to know is how difficult would it be for me to actually get test out more channels than are available with any particular model= parameter setting. Some other chipsets include model=test or model=debug, but not this one. Also, is there a tool that could help me probe around the chipset to properly identify available mixer channels? If poking the code is the only way, that's ok, but I guess it'll have to wait until I have some time available. Thanks for any pointers in advance. Best regards, -- Jure Koren, unix developer

I tried to compile latest alsa drivers anf I got make error. all the relevant information is included here. I think there is a bug in source code.

[alsa-devel] Debugged improper setting of PLL fields in WM8580 driver
by jassi brar 01 Sep '09

01 Sep '09

Bug was caught while trying to use WM8580 as I2S master on SMDK. Symptoms were lesser LRCLK read by CRO(41.02 instead of 44.1 KHz) Solved by referring to WM8580A manual and setting mask value correctly and making the code to not touch 'reserved' bits of PLL4 register.

[alsa-devel] [PATCH] new board driver to connect bfin-5xx with ad1836 codec
by Barry Song 01 Sep '09

01 Sep '09

Hi Mark, As discussed, the patch uses the original TDM order without rewriting. For the match between TDM slot number and audio channel number, a new API need be added.
