Hmm, your system is lacking POSIX shared memory as it seems. Please
ask your distro maintainers to mount tmpfs to /dev/shm with proper
access mode by default. That's required for POSIX shared memory to
work, and has been since 2001.

Some other application is using your sound device. "fuser -v
/dev/snd/* /dev/dsp*" which process is to blame.
