We made some substantial changes in WATCHOUT 6.2 in how audio is rendered. We have limited the audio output selection to a single device. This might cause problems for users that are using the internal audio device on a WATCHMAX because you can only use two channels using the WASAPI interface.
The solution to be able to output all 8 channels is to install ASIO4All and use the ASIO interface in WATCHOUT instead. It should look like in the image below:
The lower latency in ASIO might result in buffer underruns if you push the CPU too hard, simply because the small size of the buffer. It might therefore be a good idea to increase the buffer size a bit proving a better margin. Buffer underruns are heard like tiny clicks.
