Yes.

There is some noise when I send an audio file directly to the device,
i. e. cat error.wav > /dev/dsp. However, all sound programs I have
tried fail to set the audio speed (RedHat 7, tried sox, xmms, mpg123).
Sample strace output (mpg123):
...

pause()                                 = ? ERESTARTNOHAND (To be
restarted)

sigreturn()                             = ? (mask now [])
alarm(0)                                = 10
rt_sigaction(SIGUSR1, {SIG_DFL}, NULL, 8) = 0
rt_sigaction(SIGALRM, {SIG_DFL}, NULL, 8) = 0

I only tried 2.4.1 without patches on this machine which did not work
either.
