Can confirm this bug also using a HP/Compaq mini 110c. This bug seems to be associated with the Intel based soundcard since my aplay -l also has the same chipset. The wierd thing is that it worked perfectly on a fresh install of 9.04 Ubuntu. This bug started after an upgrade just last nigth (see update-history list below) with a new kernel. Switching back to the old kernel didnt fix this bug.
Reinstalling alsa did not fix this bug. Did this both via synaptics and apt-get, packages reinstalled was linux-sound-base alsa-base alsa-utils. Another observation on this problem is that the PC speaker volume control and earphone volume control both controls the volume going out to the earphones. Migth be just a pipeline bug in alsa? updatelist from synaptics: libwbclient0 (2:3.3.2-1ubuntu3.1) to 2:3.3.2-1ubuntu3.2 libxcb-shape0 (1.1.93-0ubuntu3) to 1.1.93-0ubuntu3.1 libxcb-shm0 (1.1.93-0ubuntu3) to 1.1.93-0ubuntu3.1 libxcb-xv0 (1.1.93-0ubuntu3) to 1.1.93-0ubuntu3.1 linux-headers-2.6.28-15 (2.6.28-15.49) to 2.6.28-15.52 linux-headers-2.6.28-15-generic (2.6.28-15.49) to 2.6.28-15.52 linux-image-2.6.28-15-generic (2.6.28-15.49) to 2.6.28-15.52 linux-libc-dev (2.6.28-15.49) to 2.6.28-15.52 $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog] Subdevices: 0/1 Subdevice #0: subdevice #0 -- 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
