From Ubuntu to Linux Mint 11 Xfce – Sound Problems

I decided to move to Linux Mint from Ubuntu.

The installation was quick and easy. No major trouble.

The problem started when i tried to watch a youtube video. The sound was very low.

I searched google for a while and many users had the same or similar problems.
The problem is that no solution worked for me.
Most of them suggested to use the command
alsamixer

But when i tried this i got the following error:
ALSA lib dlmisc.c:236:(snd1_dlobj_cache_get) Cannot open shared library /usr/lib/alsa-lib/libasound_module_ctl_pulse.so
cannot open mixer: No such device or address

Then I found this on ubuntu documentation.

It was a solution for fixing the microphone but when i run the command :

alsamixer -c 0

I found out that the speaker’s volume was in the lowest position. Why this happened is a good question.
