F11 - HDA Intel no sound

[atothed]

I installed Fedora 11 on my imac 7,1 twice and the sound seems to be detected wrong/does not give any sound out of the speakers and very, very low sound out of the earphones

I tried to switch everything to the max in the 'Advanced Volume Control' and in alsamixer

**** List of PLAYBACK Hardware Devices ****

Codec: Realtek ALC889A

I tried to fix PulseAudio with this guide

i'm using an 07' iMac Aluminum...and i've found that ALSA has botched the sound profile of the RealTek ALC 889A

...if this is indeed the problem... the best way to correct it is to manually specify a sound model that most closely resembles the 889A ... the 885...(Macbook Pro Revision 3)

open your fav text editor to a blank file named 'sound' in /etc/modprobe.d...you can do this in Gnome by:

su -c 'gedit /etc/modprobe.d/sound'

and insert the following into the empty file and save:

alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=mbp3

reboot and you should be good to go...

hope this helps... let me know.

hmss: have you filed a bug on your issue, with the output of alsa-info.sh (and other bits, see the pages I linked in my initial reply)? That's the only way such a problem will get fixed. thanks!

i really should...i guess i kinda hoped i wasn't the only one using Fedora on an iMac...that they would fix it as readily as some other developers do...

several ALSA major revisions have passed... and they've still made little headway to profile HDA applications properly.

on the contrary, major progress is made with HDA quirks every release. unfortunately, there's just far too many of the damn things to keep up with entirely.

Check the changelogs for the patch_* files at http://git.alsa-project.org/?p=alsa-...18050d;hb=HEAD to see just how much work goes into this.

You could also check with a Fedora 12 nightly live build:

http://alt.fedoraproject.org/pub/alt...poses/desktop/

to see if it's been fixed in the more recent 2.6.31 kernel that's in F12.
