Hi, I'm having trouble running my Line6 PODxt (module line6usb) on Ubuntu 9.04 and spent couple of evenings trying to solve it out. Everything worked perfect on Ubuntu 8.10. The device is correctly recognized by the system and PA. However, when I try to move the playback stream from my Audigy to Line6 USB I get the following dump from pulseaudio -vvv I: module-stream-restore.c: Synced. D: module-alsa-sink.c: hwbuf_unused=0 D: module-alsa-sink.c: setting avail_min=1 I: source-output.c: Freeing output 4 "Wykrywanie wierzchołków" I: resampler.c: Using resampler 'src-linear' I: resampler.c: Using float32le as working format.

I checked my groups assignments and see that it is quite correct: $ groups tomek adm dialout cdrom audio plugdev lpadmin pulse pulse-access pulse-rt admin sambashare I'm concerned about "Failed to set hardware parameters: Operation not permitted". How could I debug more what is the cause for this? If I have all the rights it might be the module issue, but on the other hand the same version worked perfect on previous Ubuntu release. Please help, I'd like to start playing the guitar :( Best regards, Tomek
