I also had the same problem. I run Kubuntu 8.10 on dell inspiron 6400. the volume hot keys did not seem to work. I noticed that when they are pressed the PCM channel volume goes up and down.
So I just selected the PCM channel as the master channel, cranked up the front channel to full...now the hot keys work perfect!! -- sound volume control broken on dell inspiron 9300 laptop https://bugs.launchpad.net/bugs/84505 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
