Fedora 13 sound problem

frsepulv · 08-22-2010, 11:31 AM

Hi,

I've a HP 420 laptop (it looks like it's not sold everywhere, here are some specifications - Spanish site: http://h10010.www1.hp.com/wwpc/cl/es...8-4158858.html) and I've recently installed Fedora 13. Everything works smoothly, except for the audio device, which doesn't output sound through the external speakers (headphones work, though).

System information:

Code:

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: HDA Generic [HDA Generic]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 3: INTEL HDMI 0 [INTEL HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

$ lspci -v | grep Audio
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)

$ cat /proc/asound/card0/codec#* | grep Codec
Codec: IDT ID 7666
Codec: LSI ID 1040
Codec: Intel G45 DEVCTG

I've pretty much read every single thread existing on the Internet looking for a solution. Google produced only one thread for this model (Spanish forum, no answer so far). Every other possible solution hasn't worked - editing alsa-base.conf with several models (hp, hp-m4, hp-dv5, laptop, auto, genric and a few others I can't recall) and options (enable-msi, single_cmd, bdl_pos_adj, etc.). I've used Windows 7 on this laptop and sound works flawlessly there.

Any help would be greatly appreciated. Please excuse my rough English, you may've realized it isn't my native language.

Thanks.

From the fact that the sound works through the headphones, we can deduce that it's not a driver issue. Have you got the pulse audio device chooser installed ? If you have, check that the output device is set correctly. if you haven't, then it's worth installing it and various other sound related tools :

Code:

yum install alsa-plugins-pulseaudio pulseaudio-esound-compat pulseaudio-libs pulseaudio-libs-glib2 pulseaudio-module-zeroconf pulseaudio-libs-zeroconf xmms-pulse pulseaudio-module-gconf wine-pulseaudio xine-lib-pulseaudio pulseaudio-utils pulseaudio-module-bluetooth gst-mixer padevchooser paman paprefs pavucontrol pavumeter

padevchooser wasn't installed, so I installed it and all those tools you suggested. After checking with padevchooser I couldn't see anything blatantly wrong with it. I attach a screenshot showing some hardware info. There is one audio device (Internal Audio Analog Stereo) which produces an input and an output subdevice and allows to choose the following configuration profiles:

Analog Stereo Duplex
Analog Stereo Output
Digital Stereo (HDMI) Output + Analog Stereo Input
Digital Stereo (HDMI) Output
Analog Stereo Input
Disabled

Excluding the info in the screenshot, this is the same data I could gather from gnome-volume-control.

Did you actually try changing any of the settings in padevchooser ? I've found that unless you specifically select a default sink by clicking on it, you get no sound.

Yeah, I've played with pretty much every option I could (clicked on all devices on the list, changed default sink, got a volume to ~2300%, etc.) Still no sound from speakers. I get the feeling this is like an "invisible headphone set" is always connected - no errors appear when I unplug the headphones (which I would expect if it tries to send sound through an non existent device) and volume monitors show normal audio activity whenever a sound should be heard.

Would it do any good if I try switching to KDE? I understand Phonon replaces PulseAudio there.
