View Full Version : [ubuntu] sound gone post upgrade

I've used Ubuntu 8.04 for some time, and I found the experience great. After reading some good things I upgraded to 8.10, but a few problems have cropped up that I simply can't resolve. The biggest one is that I can't get any sound at all in Ubuntu. I've tried a variety of fixes, but nothing seems to work. The best clue I can track down for what is wrong comes when I type alsamixer in the terminal:

~$ alsamixer
ALSA lib pulse.c:272:(pulse_connect) PulseAudio: Unable to connect: Connection refused


alsamixer: function snd_ctl_open failed for default: Connection refused


Any thoughts what I can do about this? It worked in Heron, I was a bit surprised when a couple of things stopped working in Ibex.

type "pulseaudio" in the terminal and report any error messages it gives you on trying to load.

I think this might be the same error I had earlier, but was easily fixable when I diagnosed it. :)

Pulseaudio was not installed, as I recall, I read a forum post that said to remove it. After apt-get'ing pulseaudio, I typed pulse audio and got:

~$ pulseaudio
W: ltdl-bind-now.c: Failed to find original dlopen loader.
W: main.c: setrlimit(RLIMIT_NICE, (31, 31)) failed: Operation not permitted

They were on autodetect, but I have now changed them over to PulseAudio Sound Server. No change in status.

Try


sudo gedit /etc/pulse/default.pa

And search for the following line:


load-module module-alsa-sink

If you find it, comment it out by adding a # to the start of the line, and then try starting pulseaudio again with this command:


sudo pulseaudio

Let me know if this works. :)

The line already appeared to be commented out. I added another # for good measure. I then got:

~$ sudo pulseaudio
W: ltdl-bind-now.c: Failed to find original dlopen loader.
W: main.c: This program is not intended to be run as root (unless --system is specified).
