I can't figure out how to get sound out of my computer - help! (MANUAL POSTED)
<< < (5/6) > >>
Tiger-Heli:
Disconnect the computer case headphone and mic jacks.  (especially Headphone).  Also try connecting your speakers to the black instead of the green jacks (last resort).

From the Biostar Manual:

JAUDIOF1: Front Panel Audio Header
This header allows user to connect the front audio output cable with the PC front
panel. It will disable the output on back panel audio connectors.
Pin
Assignment
1
Mic Left in

Mic Right in
4
GPIO
5
Right line in
6

But I had to view this in HTML b/c Biostar's page wouldn't let me download the PDF version of it, so can't tell you where that jumper is.

Thanks!   :cheers:

EDIT:  Also, would one of these work?  http://www.turtlebeach.com/products/micro/home.aspx  It's a USB soundcard or something.  A co-worker had one in his desk drawer for some reason and gave it to me...  Could save me the cost of a new sound card...

that speaker plug is for the internal PC speaker, for BIOS beeps and what not. USB sound card usually sound like crap but I havent tried one in years. It would theoretically solve your problem.

OK, let's see if we can work this through...  I've attached the relevant portions from the motherboard instruction manual (I have the TF7025-M2 board).

Right now I've got the pins from the computer case connected to the JAUDIOF1 port on the motherboard.  I will remove this connection.

I also have a wire connecting the DVD-ROM with the JCDIN1 port on the motherboard.  I'm not sure what this does.

On page 3 of the attachment there is a pic of JPANEL1: Front Panel Header - I plugged the power button in here but there is nothing plugged into the "SPK" pins (1-4).  I have no idea what would go here as I do not have a matching wire to plug in...

Any help would be really appreciated.

THANKS!!!   :cheers:

jaudiof1 is the connector for your front panel audio connectors.  Forget about jpanel1 it is only for your internal speaker in the PC to beep startup codes.  2 of the connectors are NC and the other is 5v and SPKR for you spkr connector on jpanel1. 

Check the connections from the front panel to the Jaudiof1 pins to make sure they are correct.

You could also disconnect the DVD audio cable since you do not need it for PC sound.  This makes sure that no cabling error in it is messing up your sound.
Green Giant:
After looking at the manual you posted, forget about the speaker inputs on jpanel1.  Actually ignore that connection all together.  The speaker they speak of are usually really really small ones that just beap and used to make that annoying AOL sign on noise.

The Jcdin1 from the dvdrom is not important either.  You can leave it plugged in.

What you want is the JAudioF1 - front panel audio header.  There may already be jumpers on that one.  I am not sure what should be jumpered if they are missing as that portion of the manual, page 6, does not show alot of information.  The most important connections are the mic left/right in and right/left line in.  When you purchased you case it should have come with instructions or with labeled wires from the front audio connections.

I know on mine my case had an extra ground input coming off the front panel audio that actually did nothing at all.  I forgot about this and when I though I pulled out the ground I plugged it into I believe a 5V power line, or something like that.  Booted up and blew the onboard sound.

If you have yet to connect anything to JAUDIOF1 then you should be ok.  

Note, your motherboard will disable the output on back panel audio connectors if you are connected to the front panel audio header.
