The recommended magic elixir for this bug is "sudo alsactl store 0". It should work, but unfortunately it doesn't.
The problem has to do with the shutdown procedures. Once the system is shut down, the damage is already done and the settings are lost. Logging out, however, does not lose the settings. Startup does not seem to be involved at all, even though that's where suspicion would point. The critical file is /var/lib/alsa/asound.state, which records the settings. By checking its modification time I determined that it was being modified during shutdown, and presumably at that time being reset to the system defaults. I tried to trace the shutdown logic that would account for this setting, but was unable to. The program alsa-utils seems to be involved. Think about it. If "sudo alsactl store 0" achieved what it's supposed to, then the last modification to the settings file would be the time that "sudo alsactl store 0" is executed. It isn't. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/270577 Title: mixer settings are lost on reboot -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
