I just installed Linux Mint 18 on my HP envy 15 and i was trying to get a nice sound using hda-jack-retask. I followed this instructions https://incognitech.wordpress.com/2013/10/27/beats-audio-hp-envy-15-on-ubuntu/ as i did for my previous distros. But when i try to apply the changes i get this error:

tee: /sys/class/sound/hwC1D0/reconfig: No such device

After that the mute led turns on and the laptop goes mute even trying to change volume (pressing the mute/unmute button seems to change the audio level on the OS but in any case the led keeps being turned on). Only after a reboot the built-in device return available (in the sound settings) and after selecting it the sound comes back.

Does anyone know how to help me? Thanks!

I had a lot of problems in the past when trying to retask jack outputs. I wrote this small post entry to remind me how I did it.

Also, make sure your device is not muted in alsamixer. You will see two red letters M (MM) signifying it is muted. In that case press 'm' on your keyboard to unmute the selected device.

  • @MGabrielli You probably did, but just in case: did you run hdajackretask with sudo? – andresgongora Oct 6 '16 at 14:46
