I recently uninstalled pulse audio and have been trying to set up JACK instead. I'm currently running my audio through a Focusrite Scarlett Solo v2. My firefox and mpd audio seems to work fine when I'm running JACK. (Haven't tried any other applications)
I was trying to change my output volume using amixer in the terminal, but I can't get any of the card numbers or anything to change the volume with as:
$ amixer scontrols
doesn't return anything.
Nothing returns for running
$ amixer
either.
$ amixer controls returns
numid=3,iface=CARD,name='Internal Validity'
numid=2,iface=PCM,name='Capture Channel Map'
numid=1,iface=PCM,name='Playback Channel Map'
So if I do try and run amixer -c 0 set Master 0% for example, it returns: amixer: Unable to find simple control 'Master',0.
I'm also not sure if this is related, but speaker-test also doesn't seem to work as it gets the error
ALSA lib pcm_dmix.c:1075:(snd_pcm_dmix_open) unable to open slave
Playback open error: -16,Device or resource busy
However when I stop JACK, it starts working.
$ aplay /usr/share/sounds/alsa/Rear_Center.wav
returns the following:
aplay: main:830: audio open error: Device or resource busy
However when I disable JACK, it starts working all of a sudden.
The output of $ cat /proc/asound/cards is:
0 [USB ]: USB-Audio - Scarlett Solo USB
Focusrite Scarlett Solo USB at usb-0000:00:14.0-8, high speed

Ok so I've just tried reinstalling PulseAudio and am just going to bother with PulseAudio now.
