Exactly what? We are already tested it our board and play the music well.
What's condition DMA aborts are happen?

As your previous mail, we can wait until this weekend. but If you
don't post the your codes until this weekend.
We assume that your works are not yet done so merge this patch first
and then fix it if your words(DMA aborts issue) are right.

Thank you,
