http://ubuntuforums.org – Hi all, After upgrading from 12.04 to 12.10 I'm unable to play any audio on my laptop. If I check the audio settings I noticed the sound card is missing on the output/input. Also in some topics it's discussed to check the alsamixer. Terminal: aplay -l **** List of PLAYBACK Hardware Devices **** card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 lspci | grep Audio 00:1b.0 Audio device: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller (rev 04) Specs: Laptop ASUS K55VD.
