Hi folks,
I would like to use my Roland Handsonic HPD-20 with ALSA on Linux.
It features an USB port which provides USB Audio and USB Midi.
Like described for other Roland products the HPD-20 gives the following
results:
* Midi In/Out both work fine.
* Audio Out works fine.
* Audio In can be selected in Pulse, but remains silent.
* Alsa mixer only shows "Midi Input Mode" with "High/Light load" values.
* When connecting the USB I get: Unable to change format on ep #84:
already in use
I've found the quirks-table.h, but I don't know what I should change there.
Any ideas how to get **USB Audio working correctly**? (It would even be
ok for me if USB Midi is not available for this instrument.)
Fun fact: Using Jack (with 44.100Hz/128/3/Jack midi must! be enabled) on
top I get audio input in applications using Jack. Though there is still
no audio mixer for it in ALSA.
Regards
Michael
