Which would explain why I now have dev.pcm.0.play.vchanrate: 48000
if bitperfect is set, while previously it was dev.pcm.0.play.vchanrate:
96000 ?

e.g. now if bitperfect is set-

AUDIO: 44100 Hz, 2 ch, s16le, 0.0 kbit/0.00% (ratio: 0->176400)
Selected audio codec: [ffwavpack] afm: ffmpeg (FFmpeg WavPack audio)
AO: [oss] 48000Hz 2ch s16le (2 bytes per sample)

previously-

AUDIO: 44100 Hz, 2 ch, s16le, 0.0 kbit/0.00% (ratio: 0->176400)
Selected audio codec: [ffwavpack] afm: ffmpeg (FFmpeg WavPack audio)
AO: [oss] 96000Hz 2ch s16le (2 bytes per sample)

No change with bitperfect=0

AUDIO: 44100 Hz, 2 ch, s16le, 0.0 kbit/0.00% (ratio: 0->176400)
Selected audio codec: [ffwavpack] afm: ffmpeg (FFmpeg WavPack audio)
AO: [oss] 44100Hz 2ch s16le (2 bytes per sample)

Device is 96000Hz 2ch s24le capable.

I thought bitperfect would disable any resampling so stream should
be the same as source or (as I thought when 96000 appeared) highest
supported by device?


Yes,

Set "vchanmode" to "adaptive".

9-stable now supports more hardware rates.
