Low sound with alsa (alsamixer options set to 100%)
 

Hi, I am using slackware 14.0 (and ALSA as far as i know). After i moved from windows xp to slackware 14.0 my sound is lower. Why has it happended ? How to increse it ? On alsamixer all is set to 100% and sound isn't as high as it used to be when i was using windows xp, why ?

I had the problem with Fedora 17. I finally fixed it by running pulseaudio-equalizer.

The following troubleshoot steps worked for me, I use USB headsets and the sound was very low in them

To test if it is the alsamixer settings that are to blame:
- At a terminal execute "alsamixer". A few things to note:
- Use F5 to show all channels of the device
- Use F6 to check all audio devices
- Set all audio levels to the desired level
- Unmute all channels (M works for the "MM" muted channels, Space button unmutes the "-----" channels)
- Exit alsamixer (press ESC)
- As root, execute "alsactl store"
- Reboot your machine. If you still hear the low volume, go to a teminal and execute "alsactl restore"
