@Dave Lentz . Thank-you for your response. I will remove the line as suggested. I won't have access to the machine for a few days now but would welcome any other suggestions or instructions to provide more reports if requested.
I should also mention I have also tried a variety of other suggestions and followed other instructions as supplied by the Ubuntu Community covering Sound bugs/problem eg checking for mute in alsamixer. reinstalling alsa/pulse. And I will confirm that this problem has only happened But I had already covered most of the bases through my own experiences in the past. Usually I have managed to resolve issues logically and methodically over the YEARS when this_similar Sound problems have occured...but this has really thrown me. Nothing obvious to me has worked. And chose to throw in this bug as it appeared very recently after minimal updating. And has not been resolved with a complete wipe of hard drive, reinstallation of 12.04 with a Canonical_LoCo provided readymade disc. One positive observation was that an addition_plugin to pulse controller( the pauv_thingy) was that the system acknowledge that sound was being played(using youtube) and the level indicator demonstrated this with a moving bar pulsing to beats. Sorry not a very good description... but it gave me some reassurance that sound data was being processed yet not being produced audibly, from the speakers. Finally. May I ask if the descriptor of the bug is correct? I am reporting that the onboard speakers no longer produce sound. However sound IS produced if I use a usb powered speaker set through the headphones jack socket. I admit I was a bit confused as what to put whilst filling out the apport requests. My bad. :/ -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1051494 Title: [, Analog Devices ID 1981, Green Speaker, Internal] No sound at all Status in “alsa-driver” package in Ubuntu: New Bug description: no sound ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: alsa-base 1.0.25+dfsg-0ubuntu1 ProcVersionSignature: Ubuntu 3.2.0-30.48-generic-pae 3.2.27 Uname: Linux 3.2.0-30-generic-pae i686 NonfreeKernelModules: wl AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
