Pulseaudio - Sound is fine on speaker but horrible on headphones

I'm using Pulseaudio with my speaker system most of the time (Two speakers and a subwoofer). It works really nice, sound is fine, everything works as expected.

If I plug in my headphones into the front of my PC, Pulseaudio recognizes that and in Pavucontrol, I see 'Line Out' change to 'Line Out (unplugged)' and 'Headphones (plugged in)' appearing. There is actually sound coming from my headphones, but it's HORRIBLE.
It's incredibly distorted. For example, I tried watching this video: https://www.youtube.com/watch?v=okpg-lVWLbE and all I can hear is the background music: the speech is completely inaudible, I just hear it as a noise. The same happens when I try opening a film locally on my PC: if there's any background music, the speech is just not audible. If there's only speech, it's still very weird and distorted, as if people were talking from underwater.

I have also noticed, that if I try 'speaker-test -t waw -c 2', both 'front left' and 'front right' are audible on both sides of my headphone (I assume that means it's playing in mono?)

I have already checked the Wiki about Pulseaudio troubleshooting, but none of the fixes worked. I have done research on the internet, but nothing changed anything.

This is my 'asound.conf'

 # Use PulseAudio by default
 pcm.!default {
   type pulse
   fallback "sysdefault"
   hint {
     show on
     description "Default ALSA Output (currently PulseAudio Sound Server)"
   }
 }

 ctl.!default {
   type pulse
   fallback "sysdefault"
 }

 # vim:set ft=alsaconf:

 pcm.!default {
     type plug
     slave.pcm hv
 }

Any help would be greatly appreciated!

Re: Pulseaudio - Sound is fine on speaker but horrible on headphones

I have the same problem with my headphones, but it does not happen always. Just a guess, do you use Firefox?

After rebooting the system and using Chromium for playback on Youtube, the sound works fine.
