I have just installed PC-BSD 7.0.1 on my notebook. Having finished the installation, I deactivated the automatic sound card detection by commenting snddetect_enable="YES" in /etc/rc.conf. Afterwards I added the line snd_uaudio_load="YES" to /boot/loader.conf to output the sound to an external USB speaker.
After reboot, I could see clearly in the middle of the initialization phase
that PC-BSD recognized my USB speaker. However at the end of the initialization
phase, PC-BSD tried to set the value of dev.pcm.0.play.vchans and I saw an
error message as follows:
sysctl: dev.pcm.0.play.vchans : operation not supported by device.
Then I opened an audio file to test the USB speaker and I did not hear any
sound at all.
Could someone please help me to solve this problem?
Below you can find some output from different commands:
