Comment (by burek):

 During a series of tests, I figured this has got something to do with
 capturing video and audio together, not only audio. That's why I didn't
 think it was a good idea to start from wav output.

 I'm also starting to believe it might be an ALSA bug actually. Because,
 every time I try to capture video from my usb webcam and audio (either
 from webcam or pci sound card), these errors are kinda normal thing to

 I'll try to capture webcam's a/v to an uncompressed a/v stream, to avoid
 possible encoders' bugs. Do you have any suggestion how to do this,
 without killing my hdd? Can I somehow stream it all using udp to some
 localhost udp port or to a /dev/null or something?
