Thanks again for your help.
Curious about pacmd, I tried the man page:
"This program takes no command line options." Hmm.
In its shell help screen it says:
"set-default-source Set the default source (args: index|name)"
Since there are several naming conventions in different layers of this, I'm
uncertain on which name variation to use. But I know it's card "0," so I try
that and it's refused. It's also index "2" according to pacmd, so I try that
and it's refused too. But this works within pacmd to check that radio
>>> set-default-source alsa_input.usb-Generic_FREETALK_Everyman_0000000001-00-Everyman.analog-stereo
Okay, is there a way to automate sending that to pacmd? Opening its shell
and pasting that in every time isn't a smooth operation, there's no way to
recall it to type it, and the index option looks broken. The pacmd man page
mentions being able to take commands in the same format as .pulse/default.pa.
But creating a default.pa with that line doesn't result in the radio button
being checked after the headset is unplugged and then plugged in again. Nor
does restarting pulseaudio from it's init.d script after creating that file.
So that default.pa's just for a full reboot of the computer?
Would it be a simple thing for pacmd's creators to add the ability to accept
as command line options what it can do from its shell? Is there any kludge
to accomplish that meanwhile?
