I am using an HP DV7 laptop (i7-2860QM) in /etc/modprobe.d/alsa-base-conf:
I commented out: # options snd-hda-intel model=auto (# added) Then added: options snd_hda_intel model=hp-dv7 Then closed the file and did: sudo alsa force-reload It came up running. The sound settings indicator applet now shows : Built in Audio Analog Surround Sound 4.0 for the output device. For the input device it shows: Built in Analog Audio Stereo (Internal Microphone) Audio is working now -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/994746 Title: "Dummy output" -- No sound in Ubuntu 12.04.
