No sound in headphones in notebook
 
Hello,

I have Mageia 1 installed in a new Toshiba notebook of this model:

toshiba satellite L750 12Z
http://ce.computers.toshiba-europe.c...UCT_ID=1112775

Upon connecting headphones in the notebook nothing happens. No sound comes from the headphones and the computer sound plays as usual.

I tryed to use alsoconf and alsamixer but nothing helped =(

The results of lspci:

Any ideas?

It doesn't even have to automatically make the main sound muted, I would be happy already if sound comes out of the headphone =/

thanks,

In many Linux distros it doesn't automatically mute the speakers when you plug in headphones, so that's not overly significant. You said you've used alsamixer, you've tried unmuting all the channels available and turning up their volume? Is there a 'headphone' channel?

Yes, I tried unmutting all channels and turning their volume up and there is no "headphone" channel. My alsamixer shows as following:

3 views: Playback, Capture and All
2 sound cards: HDA Intel PCH and HDA NVidia

HDA Intel PCH:
Card: PulseAudio
Chip: PulseAudio
Playback: 1 Channel called "Master" at 100%
Capture: 1 channel "Capture"
F5 All: just shows both channels

HDA NVidia:
Chip: Nvidia GPU 14 HDMI/DP
Playback: 4 channels: S/PDIF which is zero and I can't change with the arrows and "S/PDIF 1", "S/PDIF 2", "S/PDIF 3" which are all "MM"
Capture: Nothing

If the NVidia thing is my headphone then I am missing how to turn its volume up, but I think that not, since it says it is something for HDMI ... no idea however.

According to this, http://forums.linuxmint.com/viewtopic.php?f=49&t=82526 , providing a 'model=ideapad' option to the snd-hda-intel kernel module may be a fix.

Thanks a lot =) Mageia has no such file /etc/modprobe.d/alsa-base.conf, but I simply created it, added the line:

options snd-hda-intel model=ideapad

Rebooted, and the headphone works perfectly =) It even auto-mutes the main sound.

Greetings sekelsenmat,

I am a newbie having just install linux this morning.

Everything is working find except the headphones.

Can you explain to me, a newbie, how you created (/etc/modprobe.d/alsa-base.conf) file?

Thanks,

M E

Try this:
Press the Alt&F2 keys and then type:
Code:

sudo echo "options snd-hda-intel model=ideapad" >> /etc/modprobe.d/alsa-base.conf
and press enter.
It is probably easiest to reboot your computer to get the change to be recognised.
