New A75 user here
I stumbled on this forum after searching about info to the sound card problem.
My model is an A75-S2762. I love it and it's what I want in a laptop.
I guess I noticed the sound going out after I had placed a blanket on it while the lid was closed (hibernation mode) and the adaptor charger was on. Bad move. The laptop was hot to touch and the sound was out.
After things cooled down a bit, I got the sound back, but on occasion the sound was lost anytime I took it out of hibernation. Only a reboot would restore the sound in all cases.
I did call support and did get a quick response. The advice was to uninstall the Realtek sound drivers and install them again from the DVD. Which I did two or three times. The problem came back.
Now what I did two days ago was to go to the Toshiba Support web site and download the June 2004 Realtek driver package. I did not uninstall the drivers this time, I simple unzipped the package and ran setup. So far the problem has not returned. I hope that settles it.
<Nope, no sooner than I said that, my sound failed upon wake from hibernation
Well, back to work.
Like everyone else, I don't want to have to nuke and reimage or send it to the repair depot.
Btw does anyone know if Toshiba provides Windows XP cdroms or do I have to use the DVD?
