Hi again, The bad news is that no one answered my e-mail, the good news is that I managed to solve this myself.

If you do this yourself, you may find that 10 seconds is not enough, since this was a pretty minimal system with a SSD. A better approach would be to check 'ps' for the pulseaudio existence in a loop with a sleep 1, thus minimizing the time between full boot and starting pacat, while still being sure it doesn't launch to soon (even on slow systems). I'll have a go at that tomorrow. Best regards, Steven -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?

Start pacat on boot (or after xbmc)
Hi, I have a script that starts and kills pacat (pulseaudio cat) in order to get my USB turntable to work. It is a rather simple script, reproduced below for reference. I want to run this script at boot, but whatever I try, it doesn't seem to work. When started at boot (using an init script, or rc.local) the log it produces is always "pa_stream_drain(): Bad state". When running the script manually it works perfectly. The script is invoked with this command: su username -l -c /path/to/vinyl.sh #!/bin/bash SERVICE='pacat' if ps ax | grep -v grep | grep $SERVICE > /dev/null then killall pacat else pacat -r -d alsa_input.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00-CODEC.analog-stereo | pacat -p -d alsa_output.default > ~/templog 2>&1 fi Any ideas would be welcome.
