[Rwp] different driver modes in reaper

[Patrick Perdue]

You know what's kind of funny? Obviously, you'll get some cross talk 
with a combo mic/headphone jack like that, but it seems like the 
jacks/chips Apple use on all their stuff (iPhone, iPad, Macs) are some 
of the worst offenders. I have a junky low-end Acer Windows tablet with 
one of these combo jacks, and cross talk is almost, but not quite 
non-existent. With the same ear pods on my iPhone or Mac, it's 
noticeably much worse. The iStuff uses Cirrus Logic DAC's, while the 
cheap Acer uses an integrated Intel something-or-other. Of course, in 
this case, the D/A stage is not to blame.

Just an interesting thing.

You can have junky sequencing sessions with just the laptop, virtual MIDI keyboard, and earbuds plugged in. I’d actually consider using the earbuds mic for something, but the combo earbuds jack leaks sound from the earbuds back in to the mic, so I still must plug in a dedicated mic to record a vocal/voice over. Oh well. Can’t have it all.
