Looking for soundmodem info

Looking for soundmodem info

[Jeff Camp]

I'm looking for some resources to help me find out more about using my 
computer's sound card along with an MFJ-1275 (for keying the radio) so I can 
replace an aging TNC with something different.  Can anyone point me to some 
information on the soundmodem package?  I'm using Red Hat 9.0 with 
ax25tools, apps, and utils and have all of the ax25 stuff working great.

Thanks,
Jeff N0WJP

About the only documentation I have been able to find (other than the 
source code and man page) is:

Thanks for the info, Bob.  I spent some time scouring the internet this 
morning looking for soundmodem info.  I downloaded soundmodem-0.9-1.i386.rpm 
and installed it, but now I'm getting the following error message when I try 
to start it up:

[root@n0wjp ax25]# soundmodem -v 9
sm[1855]: x86 CPU capability 0383f9ff, MMX enabled
sm[1855]: mkiss: ifname sm0 mtu 256 hwaddr N0WJP-15 ipaddr 10.0.0.1 netmask 
255.255.255.0 broadcast 10.0.0.255
sm[1855]: audio: starting "/dev/dsp"
sm[1855]: audio: Error, cannot open "/dev/dsp"
sm[1855]: cannot start audio
[root@n0wjp ax25]#


/dev/dsp exists.  The sound card is a sound blaster compatible.  Anyone have 
an idea what these error mean?  I'm not sure exactly where to start on this 
one.

Thanks and 73,

Check the permissions on /dev/dsp.  On my system they look like this:

budr$ ls -l /dev/dsp
crw-rw----  1 root audio 14, 3 Jun 19  2003 /dev/dsp
budr$

I had to add myself to the audio group in /etc/group before I could 
use /dev/dsp.

Also check that the soundcard driver is either compiled-in or loaded as 
a module.
