 Posted: Fri Sep 02, 2016 10:01 pm Post subject: alsamixer not working when in X and not root [SOLVED] |
 |
|
This install has been going for several months now, and I haven't had any problems with sound really before now.
I'm having problems with sound now.
I have absolutely no idea what happened. I updated e2fsprogs from 1.43.1 to 1.43.2 earlier, but I don't know if that would have caused any problems.
This came after another weird (maybe unrelated but whatever) problem I had, where I couldn't login to my main user account, but could log into root and my other user account. I tried becoming root and changing the problematic user password, but I was still told that the password was wrong. I removed the account and re-added it and that fixed it for some reason. I'm only saying this because it was really odd and happened at about the same time as this alsa thing.
Basically, I can open alsamixer from a tty as both a normal user and as root, and I can open it from X as root, but I am told "cannot open mixer: No such file or directory" when I try to open it from X as a normal user.
Does anybody have any clue at all why this could be happening, or have somewhere to start my troubleshooting journey here?

Okay, I guess I was right when I wondered if they were related. I hadn't added this account to the audio group yet.
| Code: | | # gpasswd -a <user> audio |
fixed it.
I don't quite understand why it had worked from tty but not X. If I'm not in the audio group, I shouldn't be allowed to do it at all, right? And I also don't remember having done this several months ago when I made the account . . . But I guess it worked, and that's all that matters I guess (I guess ???)
If somebody has an answer to why it worked from tty but not X, I'm always interested in learning. I'm sure tagging the OP [SOLVED] is going to mean nobody's going to come look in this thread, but I'll do it anyway. |

Do you have any of consolekit/policykit/systemd installed? They perform some hard-to-understand magic in the background to check whether someone is using a "physical console" and then hand out /dev/ ACLs based on it. They seem to get it wrong more often than not.
The alternative explanation is that group changes don't apply until a fresh login, running `id` where it's not working could confirm that. |

| No, I don't. The weird part for me is how it worked in tty but not in X. But it works now after adding to audio group. I just realized I didn't tag this solved yet. |
