Yes, I have got exactly same problem, I am using a IBM X31, only after the fresh power on (even reboot doesnot work), the fresh power on means to power off the laptop, then plug off the power supply and wait for several seconds, ok, this first boot is ok, the sound is good. but after I make the laptop into hibernation, after it comes back, the sound is disappeared, so far not found other problems.
and I also found same bug reports as bug#103004 and bug #98605. It is really annoying. and, this only happens in 7.04, I used the 6.10 for several months and everything is good. -- [Feisty] Sudden sound problem https://bugs.launchpad.net/bugs/108431 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
