Ubuntu Studio: Sound not working in all applications
I have what I must describe as a strange sound problem under Linux Ubuntu Studio 14.x. The operating system sound is dead, so is sound which ought to come out of media players like VLC. Sound also fails to work in the browser. BUT, it DOES work perfectly under Audacity. I have tried to change the system settings to the same settings as Audacity, but I haven't been successful. THere was touted to be a window called "Sound Preferences", but when I clicked on the speaker icon to select "sound preferences" from the dropdown, the window that came up was "System settings", which only had icons for the printer, desktop and one other thing that had nothing to do with sound that I can't recall. Any ideas?
Are you using Alsa, OSS or the Pulseaudio wrapper. I've seen this problem where the Alsa mixer mutes the dsp channel on reboot. If you are using Alsa you can try using the alsamixer to unmute the channel and alsactl store to make the settings persistent. Hope this helps. Russell Sent from mobile.

Content-type: Multipart/Related; boundary="Message-Boundary-8768" --Message-Boundary-8768 No need to apologize. If it is the PCM channel, then I don't know how to access its information to know if it is muted or not. I noticed that alsa was installed but not running (I did a ps | grep as root). Pulseaudio was actually running. I didn't know it was a wrapper for Alsa. It appears to be standalone going by the docs (I don't see alsa or OSS listed as a pre-requisite or a system requirement).

This may be a known bug. https://bugs.freedesktop.org/show_bug.cgi?id=79911 You say alsa is not running. However I believe the sound daemon is either Alsa or OSS, although OSS seems to have been eclipsed by Alsa. Try this in order to unmute everything. amixer -D pulse set Master 1+ toggle Or you could try installing pavucontrol. https://freedesktop.org/software/pulseaudio/pavucontrol/ On 2/20/16, Paul King <sciguy@vex.net> wrote:

I guess that my solution, which I posted a little earlier, would be the strange set of mouse clicks that led me to pavucontrol. Now I know what it's called. :-) It was listed as "Pulseaudio Volume" in the menus, and the window title comes up as "Volume Control" on my system. Thanks, Russell for your help!
