This is a known, or at least longstanding, problem; I've had it since
~2.1.59 myself...

Never seen this.

strace of mpg123 ends in:

munmap(0x400d6000, 16384) = 0
write(2, "[1:10] Decoding of mlntheme.mp3 "..., 42[1:10] Decoding of mlntheme.mp3 finished.
) = 42
write(4, "4\3734\373$\372$\372Y\372Y\372\32"..., 28416) = 28416
close(4

(hanging in close on the sound device) If I ^Z then fg, it gives:

<unfinished ...>
--- SIGCONT (Continued) ---
<... close resumed> ) = -1 ENOSYS (Function not implemented)

and then exits.
