[alsa-devel] soc multi chip support
Hi,
I have 2 of the same audio codecs connected to an omap (each codec has it's own i2c address and each has its own mcbsp channel). I can configure and use each one individually, but have not found a way to configure both at the same time so that each codec shows up as an alsa device. I did some searching and found that this may not be supported yet. Is that the case or has anyone done this yet or is working on it?

ASoC multi-component support is working well, although not yet merged upstream yet.
Please pull the multi-component branch here for support :-
git://git.kernel.org/pub/scm/linux/kernel/git/lrg/asoc-2.6.git

Thanks. I pulled down the multi-component branch and am looking through it. I started with TI's latest PSP, which is based on 2.6.32, but as expected there are numerous changes between it and the the multi-component branch.
Are there any devices in the multi-component branch that are using multiple audio codecs? Just looking for a good example.

None public atm, just create your machine driver with 2 DAI links and set the individual DAI link codec driver entries to different codecs.
