So no sound from youtube.

Any ideas?

my first thought is that you've got a channel muted somewhere, or possibly the wrong sound card pegged as a default (this sometimes happens with HDMI ports).

Thanks for the reply

I thought that tii till I ran firefox-esr as root from the run... prompt and sound works fine as root

Maybe that will be a clue for someone...

I think sounds configuration files exist in the users home directory (~/.asoundrc.???) so it would have to be user configurable and per user. Perhaps try running the choose sound card option in the cc?

Maybe just add your user to the audio group?

Code: Select all

sudo addgroup USERNAME audio
(replace"USERNAME" with your user name, of course)

I looked at groups demo and audio is listed...

I think you had the right hint, Dave, so thanks.

When I find .asoundrc with mc, I see its there under demo, but not root, so I renamed the ones under the different demo directories and now test sound works from control panel. There was one folder that was read-only and I couldn't rename it there. It works from demo in firefox, too.

I guess it remains to be seen if the problem comes back after a reboot. My guess is the cause was when my persistence files ran out of space and the setups changed to fluxbox etc.

across thousands (literally) of persist-save operations, I have never witnessed"corrupted savefiles". Unless someone physically yanks the USB pendrive while it's being written to, or unexpected powerloss (and no UPS) occurs during write operation, there's essentially zero likelihood of corruption occurring. It's an atomic operation ~~ if persist-save fails, on next boot the machine state at start of session will be identical to the current session's start-of-session-state.
I was referring to the persist-save operation performed when"dynamic root persistence" (labeled"Persist root" in boot menu) is the chosen persistence type.

I've now read (in another topic) that you're using"Persist all".
That persistence mode also writes to homefs file throughout the session, realtime, as file changes occur.
Even if your system isn't connected to a UPS, the risk of homefs corruption should be no more than if its content were being written to hard disk.

I thought about it some more and I think at least one of the other machines I boot thise flashdrive from comes up appearing to have more than one sound card. Sound is still working after a reboot, so I'm good at this point and will just have to check it when I boot from one of the others.

I don't think my persistence files are corrupt.
