I have a Dell Inspiron 1501. The sound works through the speakers but nothing happens when I plug the headphones in.
I’ve been going through the troubleshooter (SDB:AudioTroubleshooting - openSUSE), but nothing is working, hoping someone has been here before & can show me what I’m missing

I did update alsa using the two repos mentioned, it made no difference so I have removed the repos & the module it suggested (using plain 11.1 from the update repo now)

I’ve changed the model in /etc/modprobe.d/sound to dell-m26 as per the alsa documents for this laptop:
options snd-hda-intel model=dell-m26 position_fix=1
# 5Dex.HbwImeQdDN4:SBx00 Azalia (Intel HDA)
alias snd-card-0 snd-hda-intel
jimtop:/home/dredd # head -n 1 /proc/asound/card0/codec*

pulseaudio isn’t enabled(via YaST > Hardware > Sound) on the card, and YaST was used to set the card up with. I did enable pulseaudio to see what it did, but nothing was any different.
My alsamixer (and kmix) show two channels for playback: ‘Master’ and ‘PCM’.
Capture has: ‘Capture’, ‘Input So’ and ‘Mux’. Input So has ‘Mic’ above it.
YaST also only shows two playback channels in the configuration screen.
I’m assuming from all this that my lappy has no idea at all about my headphones, else I would have a headphone volume control surely?
Oh, I’ve rebooted a few times, especially when removing the updated alsa-modules. Sound still works through the speakers, but not headphones. The volume doesn’t mute when the 'phones are inserted either.
Help! TIA
