I installed ubunto 11.04 (amd64) today. Same problem, VT1708/A [Azalia HDAC] using snd-hda-intel (driver)
aplay -l was showing no soundcards detected. I searched through many forums and ended up on this page. https://bugzilla.kernel.org/show_bug.cgi?id=16921#c5 go read the Comment #5 (its like:) Finally got sound using pci=use_crs on the grub boot line. Don't know what the hell this does but at least sound works and no kernel oops at boot. so what I did: I took a backup of /etc/default/grub to /root/etc_default_grub_backup then opened the file /etc/default/grub with my favorite editor vi. find the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" modify it like GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=use_crs" save the file (/etc/default/grub) after saving the file I ran update-grub like sudo update-grub then I restarted my ubuntu 11.04. yes.... perfect the sound is there!! now if you check "aplay -l" **** List of PLAYBACK Hardware Devices **** card 0: VT82xx [HDA VIA VT82xx], device 0: AD198x Analog [AD198x Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: VT82xx [HDA VIA VT82xx], device 1: AD198x Digital [AD198x Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 thats it. if you want to know more about the bug follow: https://bugzilla.kernel.org/show_bug.cgi?id=16921 Thanks Anish ** Bug watch added: Linux Kernel Bug Tracker #16921 http://bugzilla.kernel.org/show_bug.cgi?id=16921 ** Summary changed: - Soundcard not detected + [solved] Soundcard not detected -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/662299 Title: [solved] Soundcard not detected -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
