Sorry to restart this this particular thread, but I am having the same issue. I have checked all outputs, all routing etc. I can play a track as loud as I can get it in Sonar, but the exported wav file is ridiculously quiet. For example - in X3, my Master bus is on 0, and my hardware output is on 0, and my UR22 with headphones plugged in is on about 1/4. I export the file, then to get any decent volume on playback I have to turn my UR22 up to about 3/4, and even then it's still quieter than when it was playing back in Sonar. I have tried a bunch of different media players, and they are all the same. I end up having to take the track into Audacity and apply a volume boost to make it acceptable. If I put the track onto my phone, and play it back in the car, it is still too quiet. The really odd thing is that if I then import the exported file back into Sonar, its nice and loud. I feel that this should be pointing me to a possible solution somehow.....
This is really starting to get me down.....so much so that I feel it's time to start experimenting with different DAWs, although I don't really want to - I have too much money invested in Sonar to dump it, but it is starting to look like the only option.....but it looks like Sonar doesn't like me thinking about that - I tried exporting all my tracks as individual files so I could import them into something else and see what happens with the volume when I export it from my chosen something else, but every time I try exporting the tracks, I get 24 separate wav files, all EXACTLY the same size, and all of them TOTALLY SILENT. I tried using the 'audible bounce' option, and I can indeed hear the song playing while it is exporting, but I still end up with 24 tracks of nothing........arrrrgggh!
If I had hair I'd be tearing it out about now. I've found lots of questions about this exact 'low volume' problem, and it seems the usual solution is when someone realises that they haven't turned up the hardware output before mixdown, but as I said, mine is OK, so that doesn't seem to be the issue.
If anyone can assist, I will be forever grateful.....even if that assistance shows that I have forgotten something basic and I end up looking like an idiot (wouldn't be the first time!)....just help me please!
UPDATE - OK......I said I'd end up looking like an idiot....but at least I have solved the 24 tracks of silence problem. Turning off Fast Bounce solved that part of my problem. I'm guessing that there's probably something in the manual that would have told me that, so, as expected, the fault is mine. D'Oh! But I still have the 'exported track is too quiet' problem. I might now try turning off Fast Bounce and try exporting the whole mix again
Another Update - turning Fast Bounce off slightly improved the volume of the exported full mix.
