Glad to hear. Did you have to use XXX_SYSTEM_TIMER or any workaround
needed? Or, did it work as is?

Do you mean it aborts some time later after starting the stream?
Could you show the kernel messages? The default debug level should
suffice, I guess. If any, try debug=2.

How about the patch below for 48kHz?
Not sure whether 44.1kHz works at all with the current driver code.
I just guessed that the pitch parameter would handle that. But, maybe
it's not enough...

OK.
[BTW, it'd be appreciated if you add my address to Cc (or, To: my
address and Cc: to ML like other people do), so that I can check your
post quickly.]
