@Daniel Thanks for the help. After reading that article, I gather that my problem is caused by my USB soundcard not reporting the volume levels in dB properly. Although I did a fair bit of research on Google, I'm unable to find a solution to fix my problem.
In any case, my case seems to be unrelated to the problem being discussed here. Sorry for the confusion. -- volume control mute when volume is lower than 21% https://bugs.launchpad.net/bugs/443131 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
