You said you were recordings songs from the internet. Then you say:
What sound are you sending to the TV - a song playing in the web browser?All I'm doing is sending audio/video signal via HDMI from computer to the HDTV.
When the computer switches to duplicate screen mode.
Audio to Audacity cuts off.
Audio is seen on volume mixer and heard on HDTV
From what you said about Windows Media Player, you can't send a song to the TV unless you are sending video to it. You may have to live with that. So can you play a song in Audacity and hear the song on the TV when you are sending video to it?
But when you play a song in the web browser and send the video and audio to the TV, Audacity won't record it? That would be expected because Realtek Stereo Mix can only record sound playing on the Realtek device. It can't record from the HDMI device.
In that case, Windows WASAPI host in Audacity would be expected to record the song playing on the HDMI output. But your Audio Device Info does not list WASAPI, so I assume you must still be using 1.3.13. Upgrade to 2.0.6 from http://audacityteam.org/download/windows. Then try setting the playback device in Audacity Device Toolbar to the HDMI output and the recording device to the (loopback) of the HDMI output.
It's possible you have a setting in the Realtek Control Panel in the Windows Control Panel itself to determine what the headphones do. They usually have a setting to set the headphones to speaker out, so you can play a song in the built-in speakers and the headphones at the same time. *If* the headphones have a setting to take sound from the HDMI output then you can record that sound by choosing the stereo mix input in Device Toolbar. Otherwise you will have to try WASAPI.rcavictor wrote:I also discovered when using HDMI the laptop Audio-out (headphone) jack is disabled.
