I'm being sold

Belden, the company that owns my employer, Grass Valley, just announced that they are divesting themselves of us.  In all sales and mergers of employers which I've been through, I've never seen so many positive reactions.  Of course I've never worked for an overlord with this little understanding of how to run a high tech outfit.

I guess when your business centers around extruding a bit of copper you should stick to your own kind.

FreeBSD audio setup

For magical reasons, audio on my FreeBSD desktop has just worked. That was true in VLC as well Firefox. Today I plugged in a set of USB headphones and somehow expected things to just work. No such luck.  dmesg yields:

uaudio0 numa-domain 0 on uhub1
uaudio0: on usbus0
uaudio0: Play: 48000 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer.

It took some exploring but I finally found that I had to tell pulse audio what "sink" to use.  The sinks are given by the pcm number and for some reason pulse wasn't picking the device given by hw.snd.default_unit which would have been 6 in my case (see pcm6 above) but 4.  I don't know where that 4 came from.  So I did a couple of things.  First off I updated /etc/sysctl.conf to include:

hw.snd.default_auto=2
hw.snd.default_unit=6

Then I updated /usr/local/etc/pulse/client.conf to include:

default-sink = 6
default-source = 6


I still have an issue with xmixer but that's another problem for another day.
