I just installed the latest openSUSE on a new machine dual-booting with windows and found myself with no sound; I have never had this issue with other machines on Ubuntu (although it looks like I would with this Acer 5830tg) and spent hours into the night attempting to fix it to no avail. I’ve never had to deal with Alsa before so many of the commands and “install this” or “go there” are new to me. Anyway, I’ve followed the official Intel HDA soundcard help from this site as far as I can, but have had no results. I have no sound with speakers or headphones. I would deeply appreciate any help that could make this as painless as possible.
Simple mixer control 'Master',0
Capabilities: pvolume pswitch pswitch-joined
Playback channels: Front Left - Front Right
Limits: Playback 0 - 74
Mono:
Front Left: Playback 73 [99%] -1.00dB] **[off]**
Front Right: Playback 73 [99%] -1.00dB] **[off]**
From what I can read, you have your master volume muted. That guarantees no sound. Please check that setting.
Thanks. When you say “check that setting,” please help me orient a little. I’ve messed with volume in the main task-bar KDE thing (where I don’t think it was muted); in a command-line alpa tool, and various places in Yast. I am really not sure which ones correspond to what or if there is a central place to straighten it out. And, in answer to conram, Yes, I have installed pavucontrol (which is not to say I know what to do with it).
Hmmm … apologies … you noted familiarity with Ubuntu so I had thought this would be intuitive. Likely what ever mixer you have in place is muting the sound. So goto the mixer and unmute the sound.
I typically go to YaST > Hardware > Sound > Other > Volume and ensure sound is not muted there. Also, if your KDE has kmix, ensure the volume is not muted there (kmix may be the speaker symbol in the lower right corner of your KDE).
You may be able to unmute this with the amixer command … I am rusty wrt syntax … possibly
amixer set -c 0 Master 90 unmute
or something like that. If I have the syntax wrong you could search on ‘amixer’ or type ‘man amixer’ and try to figure out the sytnax that way.
I’m heading off to a different continent tomorrow for a one month vacation so my Internet access will be ‘spotty’ at best. Good luck.
You can use the alsamixer to unmute it is a commandline tool. if you wish
a nice gui for this install the xfce4-mixer it’s kinda easy to use. This is what I am using
even in kde.
HAHA! I could kiss your long-bearded faces! That little command did the trick; I guess it was muted, although it didn’t show as muted in the kmixer (plus, I assumed that “mute” would automatically show a 0 on the volume bar, like every other program I’ve used). Later I will have time to try microphone and headphones, but at the moment I am a happy man!
As far as why 3 years of Ubuntu didn’t help me with this, I never had to touch sound on Ubuntu. My hardware mute/volume buttons worked fine out of the box, and my first welcome to Linux was Ubuntu’s snappy greeting tone. But this is a new machine and I was afraid it was a GNU driver problem, whether Ubuntu, Fedora, or openSUSE.
Once again, the answer was:
amixer set -c 0 Master 90 unmute
After 5 hours of stumbling around through pages of documentation, a few minutes with you guys and now I can get rolling in openSUSE with a cheerful spirit!
Thats great news. Glad to read that. The syntax was a bit of a stab in the dark (it works on my PC … but my hardware is different).
One has to give Ubuntu credit, in that they do somethings right. Making a new users first experience better is important, and while we try here with openSUSE, we are not always up to the mark.
Glad again to read this is working. I must say, thou, you deserve credit for posting the output of the ‘alsa-info.sh’ script. Without that it would have been much more difficult to see the problem.
so my Internet access will be ‘spotty’ at best. Good luck.
