I did a fresh install of MM 10.10 beta. To get sound working, you just have to go to /etc/modprobe.d/alsa-base.conf and add the line snd-hda- intel model=imac91.
Then in terminal enter "alsamixer", and max out the volume on each bar. Then in sound preferences, go to the hardware tab and choose the "analog stero output option." Sound will work perfectly and the tinny quality is gone. The speakers finally sound how they should. It's definitely not working straight out of the box. -- New iMac (9,1, March 09) headphone jack works, speakers do not https://bugs.launchpad.net/bugs/346170 You received this bug notification because you are a member of Mactel Support, which is the registrant for Mactel Support. Status in Mactel Support: New Status in “alsa-driver” package in Ubuntu: Confirmed Bug description: I got a new iMac, (version 9,1 March 09). Everything works perfectly except the sound. Sound comes out of the headphone jack. Sound does not come out of the speakers. I've tried numerous fixes, but I think it comes down to the newest iMac hardware not being supported yet. lspci-v 00:08.0 Audio device: nVidia Corporation MCP79 High Definition Audio (rev b1) Subsystem: nVidia Corporation Device cb79 Flags: bus master, 66MHz, fast devsel, latency 0, IRQ 15 Memory at d3580000 (32-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel modules: snd-hda-intel aplay -l **** List of PLAYBACK Hardware Devices **** card 0: NVidia [HDA NVidia], device 0: ALC883 Analog [ALC883 Analog] Subdevices: 0/1 Subdevice #0: subdevice #0 card 0: NVidia [HDA NVidia], device 1: ALC883 Digital [ALC883 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 I get the same results in 8.10 and 9.04 _______________________________________________ Mailing list: https://launchpad.net/~mactel-support Post to : [email protected] Unsubscribe : https://launchpad.net/~mactel-support More help : https://help.launchpad.net/ListHelp
