Still battling away with this. But wait, there's more. From 'aplay -L':

This is just the section concerning the MBox2. There's a lot more besides about the other devices.
See attached alsamixer pic: 'This sound device does not have any controls' for the MBox2, although it does show controls under Pulseaudio V Control under the heading 'Integrated Rate Matching Hub Analogue Stereo'. I get no action on the level meters except for a heap of noise showing on the input tab which I can't hear either through the computer or the MBox2. (Pic #2) Truly baffled.
Still digging. Any required info just ask.
PS: If I launch Audacity from a terminal and set the input and output device to the MBox2 and hit record, this is the error message:
Code:
Expression 'hostFormat = PaUtil_SelectClosestAvailableFormat( availableFormats, parameters->sampleFormat )' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 1720
Expression 'hostFormat = PaUtil_SelectClosestAvailableFormat( availableFormats, parameters->sampleFormat )' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 1720
I have looked for 'src/hostapi/alsa/pa_linux_alsa.c' but can't find the file/directory.
PPS: And a little more grist for the mill; the output of alsa-base.conf:

'index=-2' which I have marked in bold on the last line of the output I tried changing to '-1'. No diff.
