FreeBSD phe.ath.cx 9.1-PRERELEASE FreeBSD 9.1-PRERELEASE #3 r244906: Mon Dec 31 16:28:46 AST 2012 root@phe.ath.cx:/usr/obj/usr/src
/sys/PHE amd64 (still says 9.1-PRELEASE, but I grabbed base/stable/9)
>Description:
With 9.0-RELEASE and hw.snd.default_auto=1 in /etc/sysctl.conf audio switched like this:
- play sound through internal speakers
- plug in headphones or external speakers and sound now plays only through the headphones or external speakers
After upgrading to 9-STABLE:
- play sound through internal speakers (works)
- plug in headphones or speakers and no sound from internal speakers or headphone or external speakers
I can force the switch by togling hw.snd.default_unit to 0 for internal speakers and 1 for headphones or external speakers.
