View Full Version : [ubuntu] Sound Volume very low

Hi there,

I have a dual boot machine here with 8.10 and XP.
Under XP my sound volume is pretty good, under Ubuntu it's very, very low compared to the output I get under XP. Thanks for VLC, which allows me to boost the output, but other apps that use sound simply don't output much at all, ie. not more than volume control allows when set to max.
My audio output is handled by pulseaudio at current, but I get the same if I use alsa or others for that matter.
Suggestions welcome on how to troubleshoot this, or anything basically telling me this is expected behavior.

I have the same problem, a fresh install of ubuntu 8.10, dual booting with windows (wubi)

on my system (i dont know about yours ryushe,) the volume output is off unless the volume level is above 75%

I had a previous install on a partition (which i removed and reinstalled through wubi) that had perfect sound output, nothing changed (that I know of) between the two installations

have you try to increase the master volume and PCM too?

I'm not sure what PCM is, but I right clicked the volume control and upped the 'headphone' output, and the volume was back.

lets see it that fixes ryushe's problem too

I have a soundblaster audigy LS and when I used windows I had the volume set to 50% and I could hear music on my way to supermarket (yes, while away from home).
Now on Ubuntu my sound volume is (almost) all the time to 50% so that I can see a movie:popcorn: on my couch or hear music.
No more music on my way to supermarket...:(

Help anybody???

right click the volume icon > open volume control > choose alsa mixer
you should see the pcm.

I'm noticing the same thing... I dual boot windows and ubuntu 8.04... I've noticed that in windows the volume is alot higher... AND I've noticed that my headphone output on the front of my computer is substantially louder than my speakers output on the back... I have checked alsa and pulse audio... it doesn't seem to matter because they're maxed out... it's definitely not a deal breaker for me because I don't like having my music too loud anyways, but it'd still be nice to know why my speakers on Ubuntu at 80% are weaker than my speakers on Windows at 25%...

i believe my pcm is max (now the sound turns off at less than 50%)

another thing i might note, sound in firefox is not working (youtube, etc)

EDIT: fixed the flash with:

that doesn't make a difference for me... it's as though the front headphone jack and the rear audio jacks have been reversed somehow... I suppose I could plug the speakers into the front headphone jack, but I'd really rather not have to do that. I'm using Hardy... are any mods familiar with this problem?
