Could it be that the card is set up for 5.1 surround instead of simple
2-channel stereo, or that you actually have the audio out connected to the
wrong output - like the rear speakers on 5.1 surround?
Most sound cards I've used come with a console that lets you set the
card for various protocols, like 5.1 and so on.
Hope it's something simple like that!
Good luck es 73

Subject: [digitalradio] Bad sound card?
Hello,
When purchasing a new radio this last week I decided to also set my
computer up how it should have been long ago. I purchased a sound card
to dedicate it to digital modes. The sound card purchased was:
http://www.microcenter.com/single_product_results.phtml?product_id=0239854
It was $9.99... I wasn't asking for the world, but I didn't think I
would get this. I am curious as to what you think? Here's the synario. I
connect the line out to my rig blaster and when I transmit I get this:
http://jeremy.cowgar.com/files/bad_sound_card.wav
This was recorded from my mom's station that is 8 miles away. Obvious
problem. I then simply moved the line out cable from my new sound card
to my old sound card that is built into my mother board. No other
changes. I do not have a recording of it, but it's beautiful, exactly
how a feldhell signal should sound.
Now, the most obvious thing would be is my sound settings wrong, i.e.
way overdriving with the new sound card or something. I set them up the
same. Looking at my ALC meter, I transmit into a dummy load, turn the
line out volume up until I get ALC movement, then turn it back down
until I cannot notice any ALC movement.
Do you have any ideas? It's just $10, but I'd really like to have a
dedicated sound card for the ham stuff, and please do not suggest a
Signalink as I already have a nice setup, all wired and working, I just
need to get this squared away. Until then, I'm working off my sound card
built into the motherboard.
Thanks for any help,
Jeremy
