Hello, I am trying a simple alsa capture on the Atmel ARM9 (SAM9G45). While only capture runs fine, putting any os call on the same thread gives XRUNs.
Even a innocent usleep(1) seems to lead to regular XRUNs. Eventually I want to dump this capture on the serial port and I am not able to get past this.
Do you test with alsa utils. If yes, where you add the usleep(1) in code?
I have tried on AT91 linux as well as on kernel 3.10.10-rt7 with no success.
I try both kernel and don't reproduce this issue with alsa utils.
Please advice, Akshay
