Description of problem: I have no audio output. I tried different solutions based on modifications upon alsamixer : - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/363870 - adding "options snd-hda-intel model=hp-dv5 in alsa-base.conf Tests : - wav fils (aplay or through VLC) => no sound - "speaker-test -c2 -Dplughw:0 -twav" => both speakers and headphones play sound - mp3 or video files (through VLC) => no sound I don't know if it is related, but mp3, flash and video files read with a player other than VLC seem to be read double-speed (I use gstreamer-plugins-bad and -ugly, and the rmp from adobe for flash files) Some system sounds work : searching a non-existant word through Firefox result in a strange sound (even if I disabled all system sounds in System > Preference > Sound) How reproducible: Always Steps to Reproduce: 1. Try to read any music or audio file Actual results: No sound Expected results: Sound played Additionnal informations : $ uname -r Linux **** 2.6.29.6-217.2.16.fc11.x86_64 #1 SMP Mon Aug 24 17:17:40 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux $ lspci | grep Audio 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03) 01:00.1 Audio device: ATI Technologies Inc R700 Audio Device [Radeon HD 4000 Series]
By deinstalling alsa-plugins-pulseaudio, all went good... (Flash videos are playing normally, mp3 and videos too, ...) I think i'll never understand the relations between Linux modules -_-"
