DESCRIPTION:
Recordings made with Beyond TV have no audio. The user may hear TV audio while a recording is in progress.
This article only applies to software-encode setups. Find your card on our list of supported tuner devices to ascertain which kind it is.
If you are using a USB device and attempting to pass audio through the USB interface rather than using one of your computer's audio input plugs, please see our Knowledge Base article on problems passing sound through the USB cable in software-encode setups first.
ARTICLE:
- Please ensure that your tuner device and sound device are both upgraded to the latest appropriate manufacturer's drivers. This might solve the problem outright. If you upgrade either of these drivers, you must run the Setup Wizard (available from the same program group as Beyond TV) again. If running Beyond TV version 3.5.0 or later, you must delete, and re-create, any Video Source associated with this card in the Setup Wizard.
- Ensure that the audio cable is connected from your tuner device's audio output to your computer's Line-In input if applicable. Then run the Hardware Setup Wizard and confirm that you are receiving audio and video on the test screen.
- Make a short test recording with Beyond TV.
- Start the volume control utility (available through your Control Panel under "Sounds and Audio Devices" and the "Advanced" button). Ensure that your "Master" (sometimes "Main" or "Volume Control") and your "Wave" (or "WAV") outputs, in particular, are neither muted nor turned down. Then, view the recording you created in step 3, using Windows Media Player, ensuring that the volume is also turned up there. If there is still no audio, please continue.
- Start your volume control utility as in the previous step. (Note: The following assumes that you are using your "Line In" input to get audio from your tuner / capture device; change as applicable.) Ensure that the Line-In (this is for playback) is muted. Change from "playback" to "recording" settings through Options --> Properties. Ensure that the Line-In (this is for recording) is both "selected" (via the checkbox marked "Selected") and that the volume bar is close to the top.
- Repeat steps 3 and 4. If you still get no audio, please continue.
Special Note to Soundblaster Audigy / SB Live! users: Your issue may be akin to that described in this knowledge base article; for that reason it is suggested that at this point you refer to that knowledge base article to resolve the problem in Live TV mode. These sound devices heavily modify the way that Windows handles audio and special steps must be taken to solve the problem.
- Please go to the Web Admin interface by opening http://localhost:8129 in Internet Explorer on the machine running BTV. Navigate to:
(In version 3.4.4 and earlier): CONFIGURE --> RECORDING --> LIST ALL VIDEO SOURCES.
(In version 3.5.0 and later): SETTINGS --> AUDIO AND VIDEO INPUTS.
From there, select the link to edit the "video source" you're using. Check the advanced settings box (v. 3.4.4 and earlier) or select "Show more options" from the dropdown at the top (v. 3.5.0 and later), and disable the "Auto Adjust Mixer" option. Finally, click "Save Changes" at the bottom of the screen. This will set Beyond TV so that it does not modify the volume settings at all.
- Ensure that the settings in your audio volume configuration are as mentioned previously (Line-In Recording selected and turned up, Line-In Playback either muted or turned down) when recording. If the hardware is functioning correctly, your recording will have audio.
If none of these suggestions helps, please make sure you are using a supported capture / tuner device by checking this Knowledge Base article. If you are using a supported capture device and are still having this problem, please contact the Technical Support department by completing and submitting the form located here.
