Playback could not be started...44.1kHz 32bit 2ch
« on: September 20, 2012, 10:01:25 am »

So my previous problem (not playing 24-bit / 96 kHz / 6 ch audio) is fixed but now I have a problem playing videos (avi, mpg, mp4). The Tag shows that it is 16bit but the MC17 error message shows 32bit. Windows does report that the sound driver does not support 32bit. TMT5 plays the video without issue. My temporary (I hope) work around is to use TMT5 to play the videos. Any ideas on how to fix this issue? Thanks.

Click the button 'Change Settings & Continue Playback' and playback will work.

You should always pick the highest bitdepth your hardware supports (24bit in your case) in DSP Studio > Output Format:

I should have mentioned that I want to retain bit-perfect audio so I don't want enable any DSP settings. If I could only enable DSP settings for certain filetypes than maybe but I don't want MC17 to mess with my HD flac audio.

Bitdepth doesn't work like that.

Please read the link I posted.

Bit depth is a property of the audio device.
If it is 16 bits you can’t play 24 without reduce it to 16 and apply dither dither.
This might be audible.
Obvious this is not bit perfect.

If it is 24 bit it won’t play 16 bit sources unless you append 8 zero bytes.
This has no audible impact as all your original 16 bits remain exactly the same.
You only shift them 8 positions towards the MSB
This is bit perfect playback.
