[SOLVED] Fast Track Pro volume control
Posted: Wed Sep 09, 2015 5:40 pm
Hello there! I've installed KXStudio over my Mint 17 and the packages seemed to install and configure smoothly, so I'm very happy with it.
There's one problem though, that I've been struggling with for over a week: I can't control my Fast Track Pro volume. At the moment this can't be done neither via hardware (FTP knobs) nor an applet.
Note that I do have sound but it's not modifiable; e.g. if I'm watching a YouTube video the only way to control the volume is from the YouTube video itself.
Volti gives me this error:
volumeicon-alsa gives me this error:
Is there any solution to this? It would be really useful to enable knobs. Thanks in advanced
Info on my hardware and configuration:
lsusb:
cat /proc/asound/modules
cat /proc/asound/cards
/home/r30/.asoundrc
/etc/modprobe.d/alsa-base.conf
