Hi. Using the pavucontrol GUI I have switched the output of twinkle from the analog output (PCI soundcard, alsa_output.pci-0000_00_14.2.analog-stereo) to a Firewire device (alsa_output.firewire-0x000aac0200e9ff37.multichannel) and it worked 100%. Unfortunately I'm unable to switch back as in pavucontrol the twinkle rows is "flashing" and no drop-down list of the sinks is displayed (no idea why). I did google but I was unable to find a sequence of shell commands that would permit to permanently "re-connect" twinkle to the analog output.

Tnx Marco
