i'm trying to use a Roland R-26 as audio interface
I saw it is now officially supported in the alsa-driver repo log
This support is not complete.
Please show the output of "lsusb -v" for this device.
$ aplay a.wav
Playing WAVE 'rabe_babe.wav' : Signed 16 bit Little Endian, Rate 44100 Hz,
-> there are no errors, but it stays like this (a.wav is a few seconds)
forever and there is no volume indication "from PC" on the device.
$ arecord -f cd b.wav
Recording WAVE 'b.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
-> no errors but the file is empty (44 bytes), the device shows active mic
level "to PC"
I guess this is one of the devices that use implicit feedback
synchronization, which is very buggy in the current driver. As far as
I know, only Jack works with these devices.
