Hello! I'm trying to forward audio from an OpenBSD 8.0 VM running on a remote server (NO SOUNDCARD) to an Ubuntu laptop over an SSH tunnel leveraging sndiod.
ON UBUNTU: Starting sndiod gives no .sndio/cookie both in user home and in root home; I start it in debug mode and get just this (working, no apparent issue) and no more output: # sndiod -dd -L localhost -m play snd0.default: play=0:1 vol=32768 dup snd1.default: play=0:1 vol=32768 dup snd2.default: play=0:1 vol=32768 dup snd3.default: play=0:1 vol=32768 dup SSH tunnel is established this way: $ ssh -R 11025:localhost:11025 -X [email protected] ON OPENBSD: sndiod is stopped and disabled, as the app should send audio directly to localhost:11025 port, in fact in .profile I wrote: export AUDIODEVICE=snd@localhost/0 in fact: $ env | grep AUDIO AUDIODEVICE=snd@localhost/0 tunnel works: $ nc -zv 127.0.0.1 11025 Connection to 127.0.0.1 11025 port [tcp/*] succeeded! I remove ~/.sndio/cookie: $ rm -rf .sndio/cookie BUT EVERYTHING I TRY FAILS: $ SNDIO_DEBUG=2 AUDIODEVICE=snd@localhost/0 mpg123 test.mp3 High Performance MPEG 1.0/2.0/2.5 Audio Player for Layers 1, 2 and 3 version 1.33.7; written and copyright by Michael Hipp and others free software (LGPL) without any warranty but with best wishes _aucat_open: host=127.0.0.1 unit=0 opt=3 _aucat_rmsg: eof aucat_init: mode refused [src/libout123/modules/sndio.c:open_sndio():133] error: Got nothing from sio_open().

I tried too: -enabling sndiod on openbsd side -removed again ~/.sndio, then restarted sndiod on Ubuntu -tried 127.0.0.1 instead of localhost in AUDIODEVICE -tried devices /1, /2 and /3 in AUDIODEVICE Any useful clues? Please don't tell me that this is because there is no soundcard on the server.... Thanks in advance! Paolo
