Tried to record a music stream using the Realtek HD Stereo Mix using Cubase 6 Elements stereo audio track on my laptop with Windows 7. I noticed a gap (silence) at some random intervals.
When I record using the Windows recorder, there are no gaps in the recording.
You are using the motherboards soundcard, possibly the worst thing you could use, you could try installing the ASIO4ALL driver, or get a proper ASIO soundcard.
As I am discovering home recording, I want to keep costs down initially and start simple and maybe this is the price I pay: latency or gaps.
My system config is a Intel Core Duo Asus latop with 4GB RAM and Windows 7 HP. Indeed, I still use the onboard soundcard made by Realtek.
The driver I use is the ASIO DirectX full duplex driver. I tried the ASIO4All driver, but that wasn’t successful as I could not start recording nor playback. Probably a newbie issue.
