Hi all

I insert one USB audio device on DM8148

when I use 'cat /dev/dsp1 > /temp/sample.pcm'

It will show '2:2:1: cannot get freq at ep 0x85'

but it still can play audio from USB audio device

How can I fixed it ~

Which Audio frame work you have used? Have you tried with ALSA frame work support.

what is the PSP release version used?

I use OSS and ' linux-2.6.37-psp04.01.00.02' on TI8148

But I set TI8168 kernel('alsa and usb') as the same as TI8148

and test audio read and write at the same time on TI8168 is test correct

thanks
