I dont quite understand how to change the line...I follwed the part about the update and that was good,,,,,but If I can refer to to the BOLD print below:
Mute Speakers when Headphones are used
* This has been a big deal for folks with Intel HDA type sound cards. The fix is as follows. Information about this fix is gotten from here.
o Update ASLA to the latest (1.0.16 as of this writing). I have instructions here.
o In your /etc/modprobe.d/alsa-base add the following line.
+ options snd-hda-intel probe_mask=8 model=lenovo
+ save and exit
+ reboot the machine and when you insert headphones the speakers will mute.
???HOW DO I OPEN /ECT/MODPROBE.D/ALSA-BASE & do I simply cut and paste?????????????????
