I have a Gravis Ultrasound "Classic" soundcard.
with all recent kernel versions, I have problems with sound. The
most aggravating: after doing a simple "cat file > /dev/audio"
the sound plays O.K. but cat hangs afterwards until it is
explicitly killed - it seems like the call to "exit" never
returns (see strace output below).
Is this proble known? (In this list didn't see any message about
similar problems) Anybody knows a solution?
regards,
Peter Daum
