Did you try other drivers, such as usb-audio?

I did not.

Then try it if you have one.

Don't have one.

It's a pity.

And, you're using user-space alsa-oss wrapper (e.g. via aoss wrapper), right? The user-space emulation and kernel-space emulation are totally different, so I have to know what you actually tried.

I'm only using the in kernel translation.

Then try aoss, too.

aoss program gives the the same garbage.

Hm, then I suspect rather it's a problem in the aoa driver side.

To make sure, check /proc/asound/card0/pcm0p/sub0/hw_params has no "OSS" entry when you're playing via aoss. If a line like "OSS Format" appears there, it is still kernel oss-emulation.

After you confirm it's a native ALSA in the driver execution, compare the parameters there between the working status (using ALSA API) and non-working status (OSS API).
