Bug Description

On builds from the 12.01 release and 191 panda-ics-gcc46-tilt-tracking-blob code, tinyplay fails to play a wav file. The file is from alsa sounds Front_Center.wav and is 1 ch, 48000 hz, 16 bit. Line out is used due to the forced default in the current audio_hw.c. The wav plays fine using the ui media player, but not at the command line. The build and the binaries are installed using the methods listed on the build job details page. The mixer values specified in 908957 were also tried without success.

This is the short log output from the 191 code:

I2C: ready
WARNING: Caches not enabled

More testing - I am narrowing this bug down. Vishal's pcm works with tinyplay, it is 2ch, 48000, S16LE. But, if you then try to play a 1ch file at 48000, S16LE it fails with the above messages on the console. After this, nothing will play correctly again with tinyplay or the music player, not even the stereo sample. It appears that this is a problem with the driver, 1) not playing a mono file, and 2) not gracefully recovering from an unsupported(?) attempt
