Hi!

I have  a programm ( terminus, a space-simulation & rpg game [ the best ;)  } ) , and
it sleeps in the following function:
---

rt_sigsuspend([] <unfinished ...>
--- SIGRTMIN (Unknown signal 32) @ 0 (0) ---
<... rt_sigsuspend resumed> )           = -1 EINTR (Interrupted system call)
sigreturn()                             = ? (mask now [RTMIN])
ioctl(19, SNDCTL_DSP_GETBLKSIZE, 0xbffffbd0) = 0
read(19,

---

( this is a "strace"-output )
What is SNDCTL_DSP:GETBLKSIZE, or better what is the BLK ??

I tried the OSS driver AND alsa and both poll this function ...
