FS#12350 - Clipv2 - Rockbox duplicates samples - effectively halves samplerate

What the title says.
At whatever sample rate I use (24k & 48k tested), each sample is duplicated.

More info since I hit submit early.
This behavior doesn't appear in the OF, which records at 24k.
I record in wavpack, but it appears in mp3 too. I doubt format is relevant.

Confirmed. However, it only happens in stereo mode. And in stereo mode, the second channel is actually a weirdly scaled and 1 sample time delayed copy of the first channel. My guess is that the code thats supposed to be mirroring the mono into stereo actually mirrors two samples into L, then mirrors two into R.
