Closed circuit: Realtek audio drivers windows 7 on Acer Aspire One AOD150

I had the issue where plugging in the headphones would not mute the internal laptop speakers.

....and will probably have it again....I don't know how I fixed but I wanted to let folks know it CAN work.

If you don't have the 3.5 mm jack in "Jack information"'s probably going to play in the speakers and headphones at the same time. Some people want that...but generally not.

I got the latest drivers from the Acer site and installed them and no go.

I ran RtlUpd.exe and then I seemed to have the 3.5 jack show up in the control panel.

Folks...this is not like the old days when plugging in headphones caused electro-mechanical switching to take place. The laptop audio port detects the headphones by resistance/impedance, so it's all electronic switching. It's a cool concept if they could make the drivers work like they should. You could potentially have the speakers on with the headphones. I've seen it work! What impedance load was being presented to the audio output amp, I don't there's potential it was lower than expected and could damage the amp, especially at higher volume levels.

ANYWAY....hope that Realtek or Acer or Microsoft figures this out.

BTW...the microsoft generic drivers seem to work ok, but I wanted the stereo mix recording source, which I think is only available in the Realtek drivers.

Fix one thing, break 2 others.

Blackberry 8800/8830 Closed Circuit Advisory


Try this site before you order a new trackball or remove the one you have now.

Also, be very careful with the retaining ring if you do remove the trackball. They are easily broken when removing or installing. ALSO, I highly recommend have a spare ring before you remove the old one. They are cheap on ebay. Pick up a trackball too...can't hurt to have a spare I guess.

The strawcleaning trick that worked the best for me was the one with the split straw end the "wings" method. My trackball is really like new again.
