Sound stuck on muted
Hi, I come across some weird problem:
If user logon with headphones / speaker lead plugged in, sound shows as muted and there is no way to enable it by clicking on speaker ikon. It is easily solvable by removing lead from port and plug it back again after user logoff and logon again.
Problem is occurring on random computers and random users, also some of them are always fine and some always muted.
Affected machines are all the same hardware HP 500B MT with the same Win 7 32bit image.
I've tried so far:
update sound driver
reinstall sound drive
Device:Realtek High Definition Audio
Driver version 22.214.171.12463 (tried some earlier versions as well)
Please see attached screenshot for more details.
Any help will be appreciated.
Had this on a few machines in W7 and resolved it by using the drivers from Realtek's site rather than the vendor.
Thanks synaesthesia, just ried Realtek's drivers but still not luck. Probably just start new image from scratch and see at which point it's failing.
ahh the realtek sound card, you'll probably find that this is down the the auto jack sensing system. It some times gets confused if someone tries to insert another pair of speakers or headphones (even in the mic socket). Unplug the speakers, delete device from workstation and restart and let the device be found again, plug in the speakers and then let it know that the output is (rear speakers). We have had this a few times.
Actually happened on a laptop the other day - we've just put up a 6m projector screen and HD projector and quad sound system put up in our drama hall. We thought we would test with laptop and Star Wars DVD. Couldn't get any sound - farting around with the amp, pre amp and windows settings, finally the sound arrives bang on cue for the start music, ableit very loud, loud enough for a fright -request new underwear lol.
Sorry for late update - forgotten post.
The issue was caused by headphones plugged in while deploing WDS image, as andyturpie wrote it's confusing the auto jack sensing system.
