Right. Perfect, this is what I needed to um, 'hear'. ;-) Thank you. Comments inline. On 2020-07-20 03:08, Polytropon wrote: > On Sun, 19 Jul 2020 19:10:09 -0700, Russell L.

However it uses alsa to access the "sound card", which I see from googling should be achievable in a bhyve vm by configuring the HDA emulation. Evidently, after consulting https://wiki.freebsd.org/SummerOfCode2016/HDAudioEmulationForBhyve and https://forums.freebsd.org/threads/what-is-the-current-status-of-audio-emulation-in-bhyve.74557/ I should be able to achieve this using vm-bhyve by setting bhyve_options="-s 9,hda,play=/dev/dsp1,rec=/dev/dsp1" in the vm template file. (Although I have no idea why the forum post uses a "9" whereas the SummerOfCode post uses "x:y" for the first entry in the config list, I'm a bhyve noob). I'll report if it works. Thanks, Russell
