What's an OK soundcard impulse response?

[CdnTiger]

I've completed what I think is a successful soundcard calibration, and numerous subsequent speaker and subwoofer measurements. I just noticed that my soundcard impulse response is not what I would expect - although I may be expecting the wrong thing!

Here are my soundcard frequency and impulse responses taken using the loopback method. Anyone notice anything wrong, or am I worrying about nothing?

Looks normal to me. You're measuring the response of a cable.......

Thanks for the confirmation. I'll be able to sleep a little easier tonight!
