I'm kind of frustrated. After upgrading from 12.04 to 14.04 I realized that the quality (especially the subwoofers) of my JBL speaker have a very poor quality. So I googled for it and found that:

Do I need any extra drivers for the Realtek waves maxx audio on my Dell XPS 17?

It had no effect in the first place, but after the updates that I installed yesterday the good sound was back! I was excited! I put my laptop to hibernate over night and this morning the sound was gone and the quality was poor again... What can I do?

EDIT:

I have a script that I must run after every wake up from hibernate:

pulseaudio -k
sudo modprobe -r snd-hda-intel
sudo modprobe snd-hda-intel model=asus-model4
pulseaudio --start

after running it everything is ok. It is annoying but I can live with that...

When the quality sound gone, set mute to your volume and turn off mute again. This quality sound stuff happens to me also and I repair it easily like that.

Also you can check alsamixer. To open alsamixer, write terminal "alsamixer" and you will see some of the sound settings.

  • Thx for answering, but that does not work for me. I have to run this script after every "hibernate session" (after restart sound is ok): [added to question] – markusw Dec 22 '14 at 18:23
  • You can automatically start that code at startup. Just search for "startup" program, open it, click to edit and write your code to "command" place. – furkant Feb 17 '15 at 03:40
  • unfortunately the modprobe commant needs sudo to be run... – markusw Feb 17 '15 at 19:34
  • A command can be run during boot as root easily. Just search for "/etc/rc.local".

    For example take a look at this link :http://askubuntu.com/questions/9853/how-can-i-make-rc-local-run-on-startup

  • But I need to run it after wake up from hibernate. Does rc.local run after that? – markusw Feb 18 '15 at 19:54
