I'm using the user space soundmodem to create interface ax0 -- so I assume I don't need to do a kissattach. When I use soundmodemconfig to test the setup, I can successfully use the PTT gui button to get my rig to transmit (and also have no problem with PTT when using Tomi's great gMFSK!). However, while i can receive APRS packets while running xastir, when it tries to transmit, soundmodem complains after the xastir info: Tx: fm AB3AP-0 to APX121-0 via RELAY-0,WIDE-0 UI^ pid=F0 =/:B7_;?z&y ab3ap@arrl.net, Avondale PA (XASTIR-Linux) sm[15891]: ioctl: SNDCTL_DSP_SYNC: Device or resource busy (16) I see the LED on my PTT interface briefly light, but not long enough to activate the rig itself before the error above is printed. I use the same HW addr (AB3AP-1) in my soundmodem.conf as in my /etc/ax25/axports file. Anyone spot what I'm doing wrong? I haven't included any .conf files since I'm not at that machine now and am hoping the above description is enough to indicate my mistake, but I'll be happy to go get those if needed. Thanks for any ideas! Mike AB3AP
