I agree that this bug is a duplicate of #461078, which I submitted on the 26th of October.
I installed as suggested by Daniel Chen the linux-backports-modules- alsa-karmic-generic. Based on the behavior of the software and the error/messages obtained by the dmesg command, I did not see any improvement at al. (see also the dmesg.txt on bug #461078, and copied in this bug report as attachment). The full alsa-info of mY amd can be seen on site : http://www.alsa- project.org/db/?f=5f1f1566912483221831d078a8a4f0d37137a1ae I installed also "alsa 1.021" obtained from alsa-project download site, and that had a large negative impact. I saw additional error messages around the codec of ca0110 chip at one side and an unknown fprintf !!!?? module, while the other hand the driver for my usb microphone (functioning very well), was not loaded. I removed the alsa 1.021 asap. Unfortunately I am not (yet) familiar with installing alpha versions of Ubuntu as ppa:thefirstm/karmic-testing. Please let me know if that is worthwhile to try. What is the difference with the alsa-1.0.21 from alsa-development?? I am not active on the alsa-project development, but googling the site I find that apparently still problems re- occurring with the CA0110 chip. E,g. http://mailman.alsa-project.org/pipermail/alsa- devel/2009-October/022130.html. Based on those mails, I have the impression that the we have to wait till the development git (if the driver is fixed) of alsa is incorporated into Ubuntu The same AMD computer is a triple boot machine with Gentoo. Similar problems are occurring with that linux version ** Attachment added: "dmesg.txt" http://launchpadlibrarian.net/34948715/dmesg.txt -- No sound on Creative Labs [SB X-Fi Xtreme Audio] CA0110-IBG https://bugs.launchpad.net/bugs/463829 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
