AA,
My final commercial product is supposed to play audio from USB. Do you
think it is a driver problem??

Try writing 0x4 to ESR when it is in the stalled state.
devmem2 0x01c01010 0x4
0x4 is the ASP transmit channel. There is likely a pending event and
writing this will manually trigger a transfer request. This gets
cleared when the channel is shutdown. Another slot may be programmed
from the ISR in the ASoC driver. This causes the channel to "stall"
when the channel is shut down. There are a couple ways to fix this
problem, but there is nothing currently in the git kernel for handling
ASoC stop/shutdown cleanly.
