Description

There are some issues with the way alsa/uclibc handles signals and mutexes.

To reproduce: install gst-plugins-base and greate a test audio that you redirect to alsa sink:

gst-launch audiotestsrc ! alsasink

It sounds like beep-beep-beep... rather than a continuos sine sound.

Workaround so far is to use OSS instead of alsa.
