[Asterisk-Users] strange problem

[Christoph Eicke]

Hi!

I have a strange problem with Asterisk (Asterisk 1.0.8-BRIstuffed-0.2.0-RC7k) 
on a VIA Samuel x86. When I make a call from the CLI either over IAX2 or SIP, 
my first call after the initial start of Asterisk works fine, even though 
upons starting Asterisk tells me "Read error on sound device: Resource 
temporarily unavailable". I hear the call over the loudspeaker. When I hang 
up (using CLI "hangup" command) and try to place another call, I get a "busy" 
signal over the loudspeaker and I get "Error reading from sound device (If 
you're running 'artsd' then kill it): Resource temporarily unavailable". If I 
issue a "hangup" again, I can dial out fine again. 
I don't have artsd running and nothing else besides Asterisk is using /dev/dsp 
(according to lsof). I have read somewhere that this might have to do with 
the sound card chip that I'm running (VIA Technologies, Inc. VT82C686 AC97 
Audio Controller (rev 50)). 
Unfortunately I don't have the luxury of getting to see the debug output 
of /var/log/asterisk/debug on that machine, because it runs on a 128MB read 
only file system. 
I'm not loading chan_alsa.so, only chan_oss.so as I think this might have 
something to do with the problem.

Any help would be great, or any hints into a possible direction.

Thanks,
Christoph
