Ubuntu thinks my Audient iD14 audio interface is Analogue Surround 4.0 when it's actually stereo. Is there any way to fix this?
I found solution in Linux Mint and Lubuntu, maybe it will work in another Linux...
- In software manager, type alsa and install
qashctl, - then in menu Sound and video find and open
qashctl, - and on the right side, Mixer device, under hw: select Audient iD14
- and on the left side under "Mixer" open Speaker playback volume and turn up volume to the top -127db and both channel work same and sound is very good.
Ubuntu (Linux in general) is correct in assigning 4 outputs as there are 4 outputs on the iD14.
As you and I both know, only one pair of outputs are physically accessible. Outputs 3&4 are primarily used to send alternate mixes to musicians and are only accessible via the Audient mixer and/or DAW. The iD14 is class compliant in as far as it is recognized and some audio can be heard. Unfortunately that is as far as it goes (currently) as there is no mixer available to ALSA or Pulse e.t.c.
If you open a terminal and run alsamixer, press F6 and select Audient iD14, it will report a broken pipe error. ALSA (or Pulseaudio) has no way of knowing how to allocate the outputs, so assumes all 4 detected outs are available, but also has no way of directing signal appropriately. It "MAY" be possible to create a new sink and assign it as stereo, but you may still get an imbalance in left and right, or worse, have left and right output on one channel only. Also, all the digital inputs and Scroll Control functions will not work.
