Not able to adjust volume

I don't think you have the sound kernel modules loaded, I thought hardy uses pulseaudio instead of ALSA or OSS by default. Can you play any kind of sounds on this machine?

Hi, I'm not able to play any sounds at all...

what does 'lspci' say about your audio hardware?

check if snd_hda_intel is loaded(lsmod | grep snd_hda_intel). If yes, apt-get alsamixergui, set volume through that. If No, load it with modprobe and set the volume with alsamixergui

I'm kinda new at this, so I don't know how to interpret it.

you have the drivers, can you install alsamixergui and set the volume? 'sudo apt-get install alsamixergui'

I installed it and got this message when opening: alsamixer: function snd_mixer_load failed: No such file or directory

???

I followed your link and did this:

sudo apt-get install module-assistant
module-assistant a-i alsa-source

then I restarted and now it works!

thank you very much for your time.
