I also experience this under 8.10 on a Toshiba Tecra M6. I actually didn't know sound was playing at all until I read this post and tried turning everything to max, putting earphones on, and listening very closely. I knew about point 2 above, but recently purchased a new hard drive (with no windows installed on it) and can now not get my sound up.
fwiw, my output from `aplay -l` is: **** 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 6: Si3054 Modem [Si3054 Modem] Subdevices: 1/1 Subdevice #0: subdevice #0 and my audio device as reported in `sudo lspci -v` is: 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02) Subsystem: Toshiba America Info Systems Device 0001 Flags: bus master, fast devsel, latency 0, IRQ 22 Memory at ffd3c000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Capabilities: [60] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable- Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00 Capabilities: [100] Virtual Channel <?> Capabilities: [130] Root Complex Link <?> Kernel driver in use: HDA Intel Kernel modules: snd-hda-intel -- snd-hda-intel toshiba u200-165 https://bugs.launchpad.net/bugs/186347 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
