    Hi,

    I’ve found a couple of problems that I don’t think are related to my hardware:

    1) If, in preferences, I change to the 64bit mixing engine (I’ve not tried this before), and audio tracks just play back as noise. 32bit works perfectly.

    2) If I try to bounce (enable offline bounce and render) any rewire track (currently trying Live 8), it’s always full of crackles/pops/glitches. Normal playback works fine.

    Thanks for any thoughts.

    (Intel core i7, Vista 64 business N, Line 6 Toneport UX8)

    Just tested, and I don’t have this problem. If you have any plugins on the track, try bypassing them.

    It’s possible that Live 8 does not like faster than realtime playback. Try realtime bounce recording instead of offline rendering.

    I’ve just done some more testing, and this happens on a brand new project, with any audio – even VSTs. Something’s going very wrong, but I’m not sure how I can track down what it is. The audio is fine in all other apps (32bit and 64bit).

    Any thoughts what I could do to get more information ? It just sounds like highly distorted/clipped versions of the audio, to the extent it’s almost pure noise.

    Is the noise present both in live monitoring and in the bounced sound file?

    It would be helpful if you can email me a short bounced wav file with the noise.

    Well, I’ve found the cause of the noise in the 64bit engine…

    My Toneport UX8 had it’s ASIO driver set to 24bit. If I change it to 32bit, it works fine, and back to 24bit, and the 64bit engine gives noise.

    I’m not sure *why*, and it hasn’t affected any other hosts with 64bit engines, but I’m sure you’re more likely to offer a technical explanation than I can 😀

    Anyway, I can live with it set to 32bit (and it’s probably better overall anyway), but let me know if you need it tested again at any time.

    Excellent tip. I checked my 64bit to 24bit conversion routine and found a bug. Please try again when 2.16 is released and let me know if you still have problems with noise.

    Thanks.

    😀 😀

    24bit driver works fine now (and I went back and tested 16/24/32 @ 32/64).

    I still can’t offline bounce from Live, but realtime does work so it’s not too bad – It would be really nice if the realtime bounce could be set to process automatically as well, on the B key.

    Thanks Frits. Great support as usual.
