Hey All,
Fairly sure this is a realtek problem -
I had some similar problems with my ASUS F3SC Laptop running realtek.
After going through this entire thread I had no luck at all (thanks anyway).
I sent realtek a lot of emails and got back some rather crap fixes (have you tried un-muting etc etc).
After CC'ing the other tech support depts, the sales team and any other realtek email address I could find I eventually got a fix from them (after having re-installed windows to no avail).
Fisrtly they sent me a file called RtHDDump.exe - this appears to send a signal to the headphones (while plugged in) to see if they respond, hence eliminating the possibility of a damaged headpone port. In my case I knew this wasn't the issue coz I could hear the ASUS jingle (in phones) when the comp was turned on.
Then....... 7 hours later I got a new file from them called RtHDmon.exe.
This fixed it!!!! sort of. I have to manually unmute the headphone everytime I turn the comp on. Not ideal, but a small price to pay for music to my ears
I'm no tekkie whatsoever, but I'm sure it happened when I had audio apps open and tried to put the comp into standby.
If you have the time to wait for a response from realtek try sending your problem to
pctech@realtek.com. CC me in too and I'll see if I can send you the files faster. Maybe they'll put me on they're payroll. lol. Include a link to this thread so they know how frustrated people are becoming with this issue.
I only hope you aren't using ASUS because they're tech support is disgraceful.
good luck
