(Fwd) Re: Ubuntu Studio: Sound not working in all applications
Some other oddments of the sound on my system: The Ubuntu online docs suggested I run aplay /usr/share/sounds/alsa/Front_Center.wav as a "fail-safe" audio file that is touted to work in all configs. It worked when: a) I was logged on as root on a console (ie, one of the ALT+# screens); b) when I logged onto a console with my joeuser account (as myself) and ran the command with sudo. It did not work when logged in as myself, as myself on X-windows, or sudoed in X-Windows under my account, nor did it work if I logged on to X-windows as root. In summary, logging in as root in a TTY has the best sound right now. On 20 Feb 2016 at 8:30, Paul King wrote: No need to apologize.

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).

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

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?

This *appears* to be fixed. The dialog I used wasn't located in any place where you would normally find the settings. 1. I clicked Audio Production | Mixers and card control | PulseAudio volume control 2. Under the configuration tab, I noticed HDMI sound was "unplugged". I don't think I was using HDMI for sound, so didn't worry about it. Below that, was a setting for "Built-in Stereo", which I set to "Analog stereo" in the dropdown. I have conventional speakers hooked up to the sound with conventional eighth-inch jacks. I wasn't sure what passed for "analog" since I thought all sound was digital on a computer. It turned out to be a lucky guess for me. 3. I set analog as the fallback device. 4. There was another tab I clicked where I had to select "analog stereo" as an output setting. I am not on Linux now, so I can't recall the tab, but I believe it was the "Output devices" tab. Thanks for everyone's help. I don't know if the changes are made permanent in any way, since I would have to reboot into linux to know for sure. Paul King

Yes their docs say it runs a sound server. What they don't say is that it is not their own. Pulse is middleware that connects to the default sound server, typically Alsa as noted here. https://en.m.wikipedia.org/wiki/PulseAudio problem the printer,
