David, What command did you use to connect? if you used something like $sudo slmodemd -c USA --alsa modem:1 home:/home/walter# slmodemd -c USA --alsa hw:0,0 error: mixer setup: Off-hook switch not found for card hw:0 SmartLink Soft Modem: version 2.9.11 Feb 5 2010 01:34:11 symbolic link `/dev/ttySL0' -> `/dev/pts/2' created. modem `hw:0,0' created. TTY is `/dev/pts/2' Use `/dev/ttySL0' as modem device, Ctrl+C for termination. error: cannot set channels for playback: Invalid argument error: cannot set channels for playback: Invalid argument error: cannot set channels for playback: Invalid argument that is what you would see. So you would need to use slmodemd without alsa mode. $ sudo slmodemd -c USA /dev/slamr0 but before that you should have done $ sudo modprobe ungrab-winmodem $ sudo modprobe slamr then run above slmodemd command and see if you could connect. Try that and report back.
