virtual_oss_cmd: Could not open control device: /dev/vdsp.ctl:

[drsnx60]

Hi,

using : FreeBSD 15.1-STABLE stable/15-n283911-b0f75189f6cb

At Boot virtual_oss subsystem starts somehow , and says :
virtual_oss_cmd: Could not open control device: /dev/vdsp.ctl: No such file or directory
Three times.
This is before its started properly by this line in rc.conf
virtual_oss_enable="YES"
After its started properly it is connected to /dev/dsp.
# cat /dev/sndstat
Installed devices:

Why or what would try to start up "virtual_oss" before its stated by its own ENABLE command ?
the webcam ?

I tried disabling virtual_oss earlier when mixer didn't find devices, which then led to having to add myself to audio group (seems relatively new; I never messed with audio group manually)

Not sure if that helps with virtual_oss though

hi, friend. drsnx60 : i have got same warning in freebsd15.1 ..
sysrc: unknown variable 'virtual_oss_default_control_device'
virtual_oss_cmd: Could not open '/dev/'
sysrc: unknown variable 'virtual_oss_default_control_device'
virtual_oss_cmd: Could not open '/dev/'

why got this message. because i have below configuration in /etc/sysctl.conf

#enable machine sound output from background of machine
hw.snd.default_unit=4

if disable this configuration ,the virual_oss warning will disappear....
xxxxxxx $ cat /dev/sndstat

pcm3: <Realtek ALC280 (Analog 2.0+HP/2.0)> (play/rec)
pcm4: <Realtek ALC280 (Rear Analog)> (play/rec) default
No devices installed from userspace.

maybe this is a bug in freebsd15.1......
