gmfsk sound error

gmfsk sound error

[Phil]

Hello,

I recently installed Mandrake 10.1 on my Asus laptop and although almost 
everything works under Linux (except for the in-built wireless link and the 
in-built camera) none of the Amateur Radio applications that use the sound 
system work.

This is the error message from gMFSK for instance:
*** opensnd: open: /dev/dsp: Device or resource busy ***

Is there a way to overcome this problem?

Soundmodem doesn't produce an error message and appears to function except 
that no sound is generated.

I probably shouldn't mention this; the equivalent Microsoft Windows 
application works without any problems at all. Still, I would prefer to use 
the Linux Amateur Radio applications since I use Linux for everything else.

Phil.

This sounds, as if there is another process using the sound device, probably 
an sound daemon (such as artsd)

To find it out, try the following as root: lsof |grep dsp

Nevery had really success with soundmodem... Latency of the OSS alsa emulation 
seems too slow for soundmodem at 9k6. 1k2 works fine though.

Thanks for the reply Luc.

The above command doesn't list any processes at all, so it looks like no 
others are sharing thesound system. Also, I had stopped any services that I 
thought might be related to the sound system but without any noticeable 
effect; I still get the same error message.

Does anyone else use gMFSK under Mandrake 10.1 on a laptop?

You must have missed something. Some sound servers release the sound 
system after n seconds of idle time.

Suggest you run up a bare-bones desktop without a sound server, e.g. 
iceWM. Try re-starting the sound sytem: 

su -c "service sound restart"

Mdk 10.0 with an Asus A2D notebook. I've never had any hassles with 
gMFSK.
