Hardwire PC soundcard "microphone boost" setting

[René]

Hi All,

Probably not entirely on topic here, but it is my opinion the
brightest minds in design just happen to lurk here.....

(and hoping to thus have put you in a favorable state of mind...

I have a Video Conference program that actively switches the soundcard
microphone boost (or "+20 dB" whatever) off. I can set it "on", but
the VC program switches it off again abruptly. It's a bug in de VC
software I cannot change, nor does the supplier feels like doing it
anywhere soon.

As a result the mike sensitivity is way too low.

Is there any application, command line, program (e.g. in startup),
that makes the microphone boost stay on no matter what commands come
in?

PC: 1.66 GHz Athlon, running XP, C-Media sound on board. Offending
program: Polycom PVX

TIA!

Hello René,

No idea. But in my experience whenever I tried something via the command
line it didn't take long until the offending program "corrected" it.

Could you share with us how good this conferencing stuff works? Does it
also work when the folks on the other side use another application?

Regards, Joerg

It works remarkably well. Less than 2 years ago the only way to do
reliable VC was using an expensive dedicated codec costing as much as
a good family car, connected trough up to 3 BRI ISDN lines.

Now I find that a fair PC + an USB2 webcam does a credible full
screen VC job over BW > 256 Kb/s over IP, even across continents.
SW endpoints like e.g. Econf, PVX or Vcon Vpoint have matured along
with the QoS state of IP connections. And work with various dedicated
codecs (Tandberg, Sony, Aethra, Codian -to mention a few I tried
myself)

Most solutions adhere to H323 standards and usually interoperate quite
adequately. SIP is also on the rise.
Most issues nowadays are with firewall traversing, but that too can be
solved.

Make your own mic preamp and connect it to the line input instead. The mic
pres in most soundcards ( esp onboard sound ! ) are shit anyway.

That's what I choose to do indeed, a one transistor phantom power
(from PC) fed preamp that fits the original mike housing. Works a
dream.
In the end it took less time than posting all these messages

Thanks all the same!
