I'm seeing the identical issue on 9.04rc (installed from repo as upgrade to 8.10 on 17 Apr), hope this can be identified as this is a IBM laptop, so I guess it's a common platform. Lenovo T61p.
It was working in Intrepid prior to upgrade.. You can switch the headphones on/off in the mixer switches, but the speakers behave as if disabled. ja...@hardline:~/Desktop$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: AD198x Analog [AD198x Analog] Subdevices: 0/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 1: AD198x Digital [AD198x Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 ja...@hardline:~/Desktop$ more /proc/asound/cards 0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0xfe220000 irq 17 -- sound only through headphones intel audio in Jaunty https://bugs.launchpad.net/bugs/349633 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
