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!
