Hi Raymond, thank you for the suggestions of things to try. Also thanks for the tip re David Henningsson's ppa and his hdajackretask:
$sudo add-apt-repository ppa:diwic/hda $sudo apt-get update [This is up to 14.04 Trusty but seemed to work well enough on 16.04 Xenial Final Beta] Played around with it (If one makes a mistake, one can press 'Remove boot override' button, shut down computer, wait a little, then power back on - should be back to where you started. Still - the only sound is the MONO SOUND from the 0x15 at the back /* LINE-2 is used for line-out in rear */ - {0x15, AC_VERB_SET_PIN_WIDGET_CONTROL, PIN_OUT}. I don't know enough at this stage to recompile kernel etc in the effort to re-introduce the 'Alc260 basic model' back in again? I will leave it at this time, but obviously if you happen to know of any changes in this situation - would be glad to hear it. Also if you / anyone else happen to hear of more things to try - please let me know - will attempt to try them out. Again, thank you for the help so far. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1562396 Title: No sound - ALC260 snd-hda-intel on Vaio VGN-A497XP on MATE 16.4 Final Beta To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1562396/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
