Same problem here, upgraded from xubuntu 9.10 to xubuntu 10.4 and have no sound except for internal system bleeps from the internal speaker. Sound was working fine before.
I have some sort of onboard sound card. I've been checking the forums for a fix and found that some people had to custom compile a kernel to fix the issue. Lots of people having this issue I think. Alsamixer sees that I have a realtek sound card but the sound applet in the notification area does not have this in its hardware tab. -- [Realtek ALC259] ALSA test tone not correctly played back https://bugs.launchpad.net/bugs/582199 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
