Comment 39 for bug 893402

>>Could you try installing this image + upgrade with TI ppa?
>Could you provide exact download links? Because there are soo many different kernels, images and etc.
Ubuntu official image: https://wiki.ubuntu.com/ARM/OMAP => http://cdimage.ubuntu.com/releases/11.10/release/ubuntu-11.10-preinstalled-desktop-armel+omap4.img.gz
Then to install TI public update: http://omappedia.org/wiki/Ubuntu_PPA

> I used Linaro Developer 12.01 and then install alsa (apt-get install alsa). To check another kernels I just download it via git, compile on my system and then load via tftp.
These images are perfectly fine, it's just that there have been very recent changes in this area, and the Linaro 12.01 image does not include the latest fixes for audio to work properly in all configurations.
