From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Need Some Help Troubleshooting Ubuntu Surround Sound (lemmy.ml)

I had sound working fine with one problem: the center and rear right channel were swapped.

I generated an /etc/asound.conf to work on the channel swap and reloaded and now I can see the audio in pulse audio monitor, but nothing from the speakers. I deleted asound.conf and rebooted and it's now back to the previous settings but still having an issue with no sound from the speakers.

Any help is appreciated. I'm still also trying to figure out how to rearrange the surround channels so they are assigned to the correct speakers. Changing them from the hardware isn't an option unfortunately.

Glad you were able to figure it out. Yeah, there are a lot of settings and different moving parts involved in doing audio. And the config files are all over the place. It can get nasty.

There has to be a way to make your settings and that pipeline the (system) default. Or at least change the profile that gets loaded for your specific soundcard and change and override the channel mapping so it won't load something else first.
