Hi,
I've got a line6 POD XT Live and ubuntustudio 13.04 and I'm having some trouble
getting things to work.
The USB driver itself seems to load fine; when connecting the USB cable, I can
see MIDI being dumped whenever I work any of the controls on the pedalboard.
When I try recording any audio in audacity, however, I'm getting the following
message:
"Error while opening sound device. Please check the input device settings and
the project sample rate." Quality settings of Audacity are at 44k1/16 bits but
I'm getting the same message at 32 bit float and 48kHz as well.
When starting audacity from the command line, some errors are logged to the
console (and as both mention sample rate, they seem to be related):
===snip===
Expression 'SetApproximateSampleRate( pcm, hwParams, sr )' failed in
'src/hostapi/alsa/pa_linux_alsa.c', line: 1968
Expression 'PaAlsaStreamComponent_InitialConfigure( &self->capture, inParams,
self->primeBuffers, hwParamsCapture, &realSr )' failed in
'src/hostapi/alsa/pa_linux_alsa.c', line: 2643
Expression 'PaAlsaStream_Configure( stream, inputParameters, outputParameters,
sampleRate, framesPerBuffer, &inputLatency, &outputLatency, &hostBufferSizeMode

Expression 'stream->capture.pcm' failed in 'src/hostapi/alsa/pa_linux_alsa.c',
line: 4525
===/snip===
I have also tried using the device via JACK, which gives this message:
Invalid container address 'driver':'channel':'(null)' supplied to method
'ResetParameterValue'..
(org.jackaudio.Error.InvalidArgs)
What could be going on? Where do I proceed troubleshooting?
Best,
Marc
