I don't really know. Though I'm certainly willing to a new kernel -
and especially if any new soundcard drivers are included! (See
below.)

I currently use the serial port for PTT (but will soon switch to
parallel so I can have rig control on the serial). And I compiled
soundmodem-0.7 from source.

That might be the problem. I'm using a several-year-old HP Omnibook
XE3 laptop from work. It has an ESS Maestro3 soundcard, which is
labeled as Experimental in the kernel config sound menu.

I gave it a try, and it keeps the PTT asserted long enough to
trigger the rig now, but still just briefly and I get the same error.

Ok, I'll go to the ALSA website and read up on it, since I've
never played with that. I'm hoping I can stick with the laptop,
but we'll see how it goes... Thanks for the help!
