[alsa-devel] Audio driver for dbAu1250 Development board
Hi
I am trying to make audio up in dbAu1250 Development board, I downloaded linux-2.6.29.4 kernel from the site "http://www.linux-mips.org/pub/linux/mips/kernel/v2.6/ " and applied the patch "asoc-v2.6.29-rc8-2009-03-17.patch"downloaded from "http://opensource.wolfsonmicro.com/~git/asoc/" but while compiling i am getting the bellow errors

before applying the patch the board was working but the audio was not working.. can you suggest me which kernel source you used and how you got the audio working for your board. can you send me the sample kernel image "vmlinux.srec" image for testing..
Thanks Manjunath.AM

Looks like the code relies on some underlying porting work which may have either changed since the code was written or may not have been merged into mainline.

This code was contributed against a much older kernel, and may well have relied on other patches. I've CCed in Manuel Lass, who contributed the code and should have a better idea what the MIPS status is.
can you send me the sample kernel image "vmlinux.srec" image for testing..
You'd be better off asking the MIPS community for this.
Hello!

For AC97, I suggest you use the "sound/soc/au1x/sample-ac97.c" driver. It does work on the DB1200 (and ONLY the db1200). If you also want I2S, I posted a set of patches on linux-mips which enhance DB1200 support; among it is a replacement audio machine driver with both AC97 and I2S (selectable through one of the board switches of the S6 group).

Please post any audio drivers for mainline here as well.
Hi Manuel,
Thanks for your reply..
I need to use the kernel for DB1250 borad..with the patches that you are suggesting will audio work on this board?? kindly provide me the link for patches that you are suggesting..
Thanks Manjunath.AM

Yes, I don't have any problems with audio playback on my Db1200. A note on I2S though: you need to unmute the "HiFi Playback Switch" in alsamixer before starting playback, otherwise the WM8731 won't provide bitclock and you'll get timeout errors on playback. AC97 works fine as-is.
kindly provide me the link for patches that you are suggesting..
At a minimum, apply these here in this order: http://marc.info/?l=linux-mips&m=124429033530426&w=2 http://marc.info/?l=linux-mips&m=124440001201703&w=2 http://marc.info/?l=linux-mips&m=124440013101823&w=2 http://marc.info/?l=linux-mips&m=124440005401759&w=2 (Db1200 audio)
The last two contain new DB1200 support and DB1200 audio system; they depend on the first two.
These are part of 2 separate patchseries I posted to linux-mips over the weekend. I'd by very grateful if you could give them a spin, Alchemy testers are very rare...
These links point to the first patches in each series, apply them in this order: http://marc.info/?l=linux-mips&m=124429030830390&w=2 http://marc.info/?l=linux-mips&m=124440000101690&w=2

Thanks a lot, surely will test and comeback to you!!!
