I'm trying to simply output and audio file via the ARM, I think this should be ok but the audio is always choppy. Am I doing something wrong? Or perhaps should I use only the DSP processor to play the audio? (didn't tried this yet because I need the DSP to do other tasks).

We did write our own AIC23 drivers which we used directly from our application. We used a device entry (/dev/aic23) that hooked in our driver. We were able to open those in any application and play/record or both. The only possible problem was if we tried to do things like "cat file.pcm > /dev/aic23". Although this would work, some cases would not work due to those applications buffering schemes. For example, this was bad: "cat /dev/aic23 > /dev/aic23". It would work, but would be choppy. How are you playing audio?

I'm using the AIC23 driver bundled in the OMAP kernel, I tried playing through OSS directly to /dev/dsp (which gives me the best results, choppy sound though) and through ALSA which is similar. Doing cat test.wav > /dev/dsp or /dev/audio just gives me noise output. And I still can't record anything. I've tried every player possible.

Unfortunately I'm still nowhere to get the problem solved. I'm stuck in this underrun problem.
