Low volume on Acer Extensa 4420 laptop

Postby vinoman on Sat May 02, 2009 7:14 pm

I've never been able to turn the volume up on this Acer Extensa 4420 laptop. The volume is at 100 and its still hard to hear. Is this a Pulse audio problem with the sound card on this laptop? Should I use another audio program instead?

I don't like having to use Vista to hears things on this laptop! I'm running Mint 5.

What am I missing?

Check for a PCM control or slider and set it to about 1/2 to 3/4 at first. Adjust accordingly while listening, but remember too much PCM can cause distortion if the volumes of the app and main are set too high along with PCM.

You should be able to do this from alsamixer in terminal as well:

Code: Select all
alsamixer
f1 for help menu while in terminal.

I found a CL program called Rexima. I found another volume control that was low so I moved it up and my volume is a little better than before.

Glad to hear you've partially fixed the problem :)

the actual command your need is:
Code: Select all
alsamixer -Dhw


and then make sure that the out put looks similar to mine if not just adjust it :wink:

Hi Carl

Can you tell me what the "-Dhw" option does when used with the "alsamixer" command as I am unfamiliar with that option being used with alsamixer????

I looked at the alsamixer man page before posting this question:

I was unable to find that option listed.

to be honest I don't have a clue :lol: but it produces the above screenshot and allows you to adjust all the sound options as typing "alsamixer" in anything above Ubuntu 8.4 will only give you one slider :?

Oh I see. Must be something particular with your type of sound card maybe or Nvidia, but as long as it works for you thats good. In every Linux Ive always just used the command "alsamixer" and I get a full terminal view with all controls. This is mine using the command alsamixer

I have seen some PC's with fewer controls, but this is usually caused by the sound card limitations or its lack of support by the OS.

Ok thanx for the reply. I just thought that I might be missing out on a different command option for alsamixer that I didnt know about.
