Sorry for the delay on this, it has been a busy month. I'm finding some
time to get to this.
I enabled UAUDIO_DEBUG and got some info. Here's what I got from
/var/log/messages when I started sndiod w/ debugging & started
running aucat

I hope this reaches you. I think my mail server is having troubles
communicating with the mailing list. I changed the rate and buffer
size using aucat, not sndiod, and that changed the rate. I have
the .wav attached. Also of note, I pasted the wrong aucat command
I ran. It should be
$ aucat -f snd/1 -o - | aucat -i -
or
$ aucat -f snd/1 -o output.wav

To debug this, you really need to change sndiod options. There is
buffering at every software (and hardware) layer and we need to tweak
the uaudio(4) operating mode (I'm suspecting the driver, which is the
only layer whick behavior depends on the hardware in use).
To do so, I'd suggest to stop sndiod(8) and run in on a terminal with
the '-dd' options. This allows to quickly tweak the device modes. Example:
$ doas sndiod -dd -z 256 -f rsnd/1
^C
$ doas sndiod -dd -z 320 -r 16000 -f rsnd/1
^C
...
FWIW, you can see the hardware operating mode by running this command
while the device is recording:
$ doas audioctl -f /dev/audioctl1
name=envy0
mode=play,record
pause=0
active=1
nblks=2
blksz=240
rate=48000
encoding=s24le4msb
play.channels=2
play.bytes=5464320
play.errors=0
record.channels=2
record.bytes=5464320
record.errors=0
Unless this shows what's going on, the next move will be to build a
kernel with UAUDIO_DEBUG and see if there are warnings on the console.
