No more sound in my headphones after unpluggin USB headset

[pmario]

Hello,

yesterday I had the possibility to test an USB headset and it worked perfectly. The problem is that since I detached those headsets, my headphones (the jack exit) are mute even if they are not mute and the volume is set to 100%. Under pavucontrol I see the headphones when plugged but modifying the volume has effect on the speakers (!) not on the headphones! What detaching USB could have changed and, more importantly, why?! I already set the card, unmute both master and headphones and set both volumes to max with alsamixer.

Some informations about my system: I have an intel sound card:

Code: Select all

First what I do when this happens is reboot. then I open a command prompt and enter

Code: Select all

alsa force-reload

I know its annoying to have to do this... but I have not found another fix yet



P.S. Im quite furious at the sound problems I have with LM16

DONT GET ME WRONG Linux Mint + Kali/BT are the WINNERS!!!!!!! (imo they are the bestest)

hi guys

I am not sure if you have found a fix but I found a temporery fix so that sound works on your VT1802 card

have a look, post #2 - #4 for indepth details https://bugs.launchpad.net/ubuntu/+sour ... ug/1318434

in short:

• add or modify your alsa-base.conf file(the last line) to llok like this

  Code: Select all

   options snd-hda-intel model=auto indep_hp = true

  reboot
  sleep the system
  wake it up again
  sound works (hopefully)

I hope this works for you guys, been looking for a fix for this for a couple of years...
