I have an ACER Aspire 4920G Lab top with XP SP3 and Realtek AC 97 drivers installed.
Everything works fine except I can't get any playback on the speakers from the line in (or mic) entry. It is strange because the recording works fine with both.
I tried to use windows Volume Control, but the audio output "Line In" does not show. (it does on other computers)
Using Volume Control -> Options -> Properties, I can choose to show:
- Master Volume
- SW Synth
- CD Player
- PC Beep
but nothing for line in...
Same using the realtek software.
I know on some setups, the only way to play back the "line in" and "microphone" streams is to do the following (this is for Vista, but should be the same for XP)
Open Control Panel -> Sound -> Recording
Right click on "Line in" (or "Microphone) -> Properties
Under the Custom tag, make sure "monitering" is enabled. This plays back whatever stream comes through to you're default output device.
