I tried this out, finally got a chance to play around with recording guitar or voice to a track, in the past it never really worked for me, so just used BIAB or Reaper (BIAB 2021, #822).

In short - close to a disaster. The recording worked ok (Focusrite 4i4, Shure SM58, guitar, USB ASIO drivers, 44 or 48khz) but playing back right after the recording caused one of these 3 issues (and I tried this both on my laptop as well as on my PC):

- BSOD (I hadn't seen that screen for at least 5 years), I nearly spilled my coffee
- an Access violation at address 00007FFD2CA5C830 in module 'libfastdsp.dll'. Read of address 0000000000000000 error
- a BIAB error saying that the Windows Audio driver had changed (about 2 seconds into the playback)

Interestingly, when I saved the BIAB track right after the recording, and rebooted my PC and started BIAB up again, it played back beautifully through the same audio device.

I also recorded the same guitar/voice through Audacity and Reaper, plain recording, and it played back ok.

This took me almost 2 hours, luckily slow day at the home office.
I emailed BIAB support the Access violation error details.
Could be me, my setup, audio device, who knows - but both recording and immediate playback worked without problems in Reaper and Audacity using the exact same Windows audio settings.

It'd be great if we could get somebody else to give this a try - I dare say that it will probably work for them :-)
