Hi David, Raymond, thanks for your follow up. Here is more pertinent information:
Changing from "Multichannel output" to "Multichannel input" on the Output tab in gnome sound settings makes the UA-101 output device disappear completely and permenantly and it does not appear in the Input tab. The only way to restore it is remove pulse files from home directory or use pavucontrol. Checking pavucontrol in this instance shows that the profile for the card has actually been set to "Off" rather than "Multichannel Input". Changing the profile in pavucontrol for the UA-101 to "Multichannel Output" shows a 10 channel output device, set up with 10 channel output device (with 8x 7.1 surround channels and 2 auxs) in the Output Devices tab of pavucontrol and a 10 channel input device called "Monitor of EDIROL UA-101 Multichannel" set up with the same channel names as the outputs in the Input Devices tab. Changing the configuration profile to "Multichannel Input" and the UA-101 device disappears completely and there are no devices representing the UA-101 in either the Output or Input tabs of pavucontrol. Using Jack2 and QJackCtl works, creating 12 inputs and 10 outputs. QJackCtl log is as follows: 6:11:26.234 Patchbay deactivated. 16:11:26.236 Statistics reset. 16:11:26.239 ALSA connection change. 16:11:26.244 D-BUS: Service is available (org.jackaudio.service aka jackdbus).

Looking at the circuit diagram on the top of the UA-101 shows that it has 10 inputs (two of which are optical inputs) and 10 outputs (two of which are optical outputs) as well as 2 monitor output channels - this determines that there are in reality 10 inputs and 12 outputs....... :/ confused :S The circuit diagram can be seen here: http://media.soundonsound.com/sos/may05/images/edirol3diagram.l.jpg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/986817 Title: UA-101 - UA-101, playback Pulseaudio fails to detect card To manage notifications about this bug go to: https://bugs.launchpad.net/pulseaudio/+bug/986817/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
