I'm reading many reports that this no longer works on that audio chipset.
For some reason, I am unable to record streaming/playing audio directly from my speakers on my computer using Audacity (Version 1.2.6).
The dropdown list which allows you to select your preferred recording / input device / port is grayed out and inaccessible on my computer, and I am not sure why seeing as I have installed Audacity before on a couple other machines with nothing like this happening.
I am using an Acer Aspire 6920G notebook PC, equipped with a Realtek HD audio card for both the built-in speakers and any line-in/out and HDMI devices. I have also hooked up external speakers ("analog" using the old one-pin green-colored jack), which have not remedied the problem.
I have tried switching inputs from the built-in speakers to a Line-Out device (my external speakers and subsequently my microphone), while also switching the audio source via Windows Vista's Sound Panel between the "Speakers", and "Realtek Digital Audio Output" (Optical and Line-Out). None of these attempts have restored the dropdown list, nor have they enabled me to record any audio from any device.
I have also checked and double-checked my Audacity preferences for Playback and Recording; the only options I am given for Recording devices in Audacity is either my Microphone (from the Microphone jack - listed under Realtek), or the Microsoft MIDI Sound Mapper; As stated, I wish to use my external speakers or built-in speakers to record audio coming from them -- so the Microphone option was of no use, and the Microsoft MIDI Sound Mapper of course failed to give any evidence of audio from any device or port when recording.
Is there something else that I'm missing or another way I can go about this? I appreciate the help.
