new ubuntu install - low sound

[Bender]

I installed the latest ubuntu release on my wife's old computer. She has been d/l mp3s with limewire and it is working fine. However, when she plays mp3 songs (rhythmbox, audacious, or whatever) the sound is much lower than when she was using win 2000 on the same machine. Also the left speaker has no sound at all.

We have gone into the volume control properties, and made sure the sliders were all up.

I have googled the problem and found many other people with the same ubuntu complaint. I also read about the etc/modprobe.d edit where you add that extra line near the bottom... I have not tried that yet. I will later today.

any other tips? The wife is mad...

The wife is mad...

what's new? haha.

anyhow i have never run into that problem so i can't be of any help, sorry.

i'll ask my buddy later if he's experienced that problem with his setup. i'll get back to ya.

If you found help on the internets, you aren't going to find any better here. Sound has been among the most flaky things about Linux in my experience. Fonts are equally flaky.

When you are editing configuration files, make sure you save the previous version.

I used linux myself for several years, but not recently... I remember having a couple issues with sound, but from what I remember, it was just a matter of finding the audio sliders and moving them all up. I don't remember having any complicated audio problems. I used RH9, Fedora 2, 3 & 4, Mandrake/Mandriva, and Debian.

I was hoping that the latest ubuntu release would have no basic problems (sound, etc).

I think I'm still a member of a couple of linux boards, so I will look for info there.

Did you try the headphone jack (if you have one) to see if that is working at a proper volume? Just a thought. We're trying to get as much info as possible here.

What's the output when you run the command lsmod ?

I haven't actually messed with it at all yet. Tonight after work I'll sit at her ubuntu machine and check it out.
I don't think there is a headphone jack, just the normal speaker out/ audio out.
It's a home-built machine I did for myself quite a while back. Not sure if it has an audio card, or on-board audio. I'm thinking on-board.

I'll try the "3stack" thingy too.


i fixed it...here was the solution....

adding to /etc/modprobe.d/alsa-base

options snd-hda-intel model=3stack

edit: slightly off topic, but what the hell does "sudo" do? Last night my wife was logged on her ubuntu machine, and I sat down to try to edit the modprobe.d file as above... I went into terminal to sudo gedit it, and ubuntu asked me for the password. I entered my (root) password but it would not accept any characters at all. Was this because my wife was logged on? what's the point of sudo if you have to log out the regular user, and log back in as root??
Same thing when she is logged on, and wants me to install stuff (synaptic). ubuntu asks for the password. I type in the root password (my password created during install). Not accepted. Try her password, not accepted. If I log her out, and log back in as myself, synaptic and everything works fine.

That's only going to work if you're using that driver. If you're using that card, the following command will show it (driver is called snd_hda_intel):

lsmod | grep snd_hda_intel

You'll get something like


snd_hda_intel 384176 4
snd_pcm 83204 3 snd_hda_intel,snd_pcm_oss
snd 63268 16 snd_hda_intel,snd_pcm_oss,snd_mixer_oss,snd_pcm,sn d_seq_oss,snd_rawmidi,snd_seq,snd_timer,snd_seq_de vice
snd_page_alloc 16136 2 snd_hda_intel,snd_pcm


as the result if you're using that driver. Intel's HD audio driver was a huge pain in the ass to setup on every Linux I've ever used other than Ubuntu. :lol

man I'm rusty with linux. a couple years ago I knew more about this stuff. Ok, I'll find out what's under the hood when I get home.

edit: slightly off topic, but what the hell does "sudo" do?

man sudo (http://pwet.fr/man/linux/administration_systeme/sudo)

[Bender]

guess I have to learn about sudo.
As mentioned in the previous "distro recommendations" thread, I never had experience with sudo with the distros I was using (Fedora, Debian, Mandriva).

regarding the low sound... it is higher than it was at first... Not sure what my wife did, or I did. It is still lower than normal, however that is probably because the left speaker is not playing.
