Edirol UA-101 card is not autodetected by PulseAudio and the driver is not
loaded.
Therefore it cannot be used using PulseAudio without manual interaction (See
workaround).
It works properly when accessed directly via ALSA.
There is a workaround to load the pulseaudio driver manually with the following
script: (I have turned the frequency selector to 192kHz.)
#!/bin/bash
echo 'load-module module-alsa-sink device_id="'$[$(cat /proc/asound/cards |grep
UA101| cut -d'[' -f1)]'" rate=192000 channels=6
channel_map=left,right,aux0,aux1,aux2,aux3' | pacmd
The UA-101 is an USB device that has a hardware switch to select sampling
frequencies:
192000 Hz, 6 Channels
96000 Hz, 10 Channels
88200 Hz, 10 Channels
48000 Hz, 10 Channels
44100 Hz, 10 Channels
When using 192000 Hz sampling rate, only 6 channels are supported, while
otherwwise the card supports 10 channels.
