audio_output {

audio_output_format 48000:16:2
rc.conf.local on the output boxes:
sndio_flags=-U 0 -L -
Bonus feature: turn both of them on and the slight lack of sync between
outputs turns into reverb which makes your house seem 10x larger (then
turn one of them off because they will keep drifting apart and it
becomes really annoying). Maybe different buffer sizes will fix this,
but I never bothered to check.

We don't have the necessary code to synchronize two audio devices.
Changing the buffer size wont fix the drifting

Thanks for the info. I reckon it would be quite an undertaking to sync
audio devices over (different) network connections -- especially on wifi,
as in my case --, I just wondered if changing the buffer size would make
a difference.
Anyhow that isn't really important (and if it were, I'd get wireless
speakers or something like that), I'm more than happy as it is. Thanks
for the great work, Alexandre.
Listening to a CD over the net
Since I seem to be the only person using this feature (with the possible exception of ratchov@ himself), here's a periodic reminder that you can use sndio OVER THE NETWORK. Optical drives are kind of passé, but I still keep a working USB one around. I hooked it up to a convenient machine--an old sparc64 with USB1.1, as it happens--slotted in an audio CD, then took my laptop and went into a different room. On the laptop I restarted sndiod with -L-, then ssh'ed to the machine with the CD and ran $ AUDIODEVICE=snd@laptop/0 cdio cdplay ... and that's it. Music in my laptop headphones. Because we can. Sndio doesn't have any built-in authentication. You can use ssh's port forwarding if you don't want to run it over the naked network. In my case, IPsec over the WPA2-secured wireless seemed enough. -- Christian naddy Weisgerber na...@mips.inka.de
