[SOLVED] Too many audio channels in alsamixer and mute speakers
 
Hi,I'm new in this forum.
I'm running Debian Squeeze on an old Fujitsu Scenic c610.
When I try to plug my speakers' cable (jack 3,5) in the headphone port of the machine,no sound gets out.
This is my sound card
Code:

00:1f.5 Multimedia audio controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller (rev 02)
        Subsystem: Fujitsu Limited. Device 122f
        Flags: bus master, medium devsel, latency 0, IRQ 17
        I/O ports at 2c00 [size=256]
        I/O ports at 2800 [size=64]
        Memory at d0080c00 (32-bit, non-prefetchable) [size=512]
        Memory at d0080800 (32-bit, non-prefetchable) [size=256]
        Capabilities: <access denied>
        Kernel driver in use: Intel ICH

My user appears to be added to the audio group,and have alsa installed.
I've tried to manage it to work since yesterday,at the bottom of this thread ( http://www.debianizzati.org/phpbb/vi...c7a0e59299be79 ) you can find a screenshot of all the available channels in kmix.
Hope you can help me to find the correct audio output in the list,because in a previous installation audio worked with ubuntu,but unfortunately i don't remember how to set channels correctly.Please forgive my bad english.Thanks in advance!regards

Alsamixer...

Use the command "alsamixer" in a terminal to open the full version of the alsa controls as a GUI. You should be able to change the output to try to find which one controls the output jack you're using. Try several; the names assigned to the different jacks are not necessarily correct.

Hi thorkelljarl and thanks for your answer.
Success!
This is what i did:
Code:

rm /var/lib/alsa/asound.state
/etc/init.d/alsa-utils restart

then I followed your suggestion and found the combo,checked
1.Line jack sense
2.Headphone jack sense
3.PCM
now I'm listening a song with my debianbox :)
thank you again! regards.
