This is not something I've played with, so it make take a few tries to get it right, if it's going to work at all.

For starters, enter this in the terminal gksudo xed /usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf and when the file opens find this section:

Code: Select all

[Element Speaker+LO]
switch = off
volume = off
Change it to this:

Code: Select all

[Element Speaker+LO]
switch = mute
volume = merge
Save the file, ignore the warnings from the terminal, reboot and test the sound.

Be aware that at first, the Line will probably be muted. You can unmute it however you wish, and it will hopefully work. The amixer toggle command should be both quick and sufficient.

If there's still no difference, do the above again and change mute to on then save, reboot and test.

Yes, that worked. I now have 'phones working on both headphone and line outputs. I had to use alsamixer as you described. Must be progress!

Okay, I think we're just about all set.

If you change mute to on, I believe you'll have sound going through both outputs at all times.

There could be some finicky situations where you unplug something and the other doesn't behave right away. Or it could happen only when plugging something in. I believe all should be "fixable" via alsamixer now.

Play around with it some and see if there's a scenario where you don't like what's happening and I'll see if we can improve it even more.

It seems, your system was turning off the Line when Headphones were recognized, and not ever turning it back on. If you leave the setting to mute instead of on, I believe sound will play on the Line out port until headphones are plugged in, which will then mute the Line, but still be unmutable. When the headphones get unplugged, it should automatically unmute the Line.

Hope that all made sense.

Have changed to 'on', it's still working! Wow, that was a real mission, and many thanks for your patience.

I'm happy to help!

I believe the reason your sound worked until it didn't might have something to do with the Card 0 Device 0 vs Card 0 Device 2 in some of your outputs. In fact, now that you've re-installed the sound base, let's see if dmesg | grep snd still reports Device 2. I'm somewhat expecting it still will, but at least we found a way around your issue.

One thing to make note of. If there's ever an update to the package that controls the files /usr/share/pulseaudio/alsa-mixer/paths, you may need to make the same change again. I presume it's PulseAudio that controls that, and I doubt we'll ever see any more updates on our old 8.0 version of it, but just wanted to make you aware.

Apologies, not looked here for weeks - getting on with life! Just a thought, I have a pc tower I can fit out from scratch. If I was to buy a mobo (used and cheap) what would be ideal for Mint? Where would I go for this info? I have googled and there's not a lot - most say check out each mobo, but given that they will work on one release and then not the next, I need to be sure I have good info. I don't need state of art. 10 year old is fine but it needs to gell with an available and supported release.

I couldn't give you an answer for the mobo. I don't even know what my system is using (and yes, I could easily check, but it wouldn't mean much to me.) I'd suggest starting a new thread for that, so people that know that stuff will see it and hopefully reply.

Your output was as I suspected it would be. Most likely a BIOS issue, but at least it doesn't really matter now.

Good luck to you! :D
