Hi Mike

Importantly, I can now jam a CD-ROM in the slot and play audio. Which, of all things, in this case, is not controlled by the slider volume control on the PMMixer for CD-ROM. It is controlled by the PHONE volume slider! Sounds like the port I/O issues are garbled for the PMMixer application. I've not tried the complete test run for the UNIMIX command line operation, nor have had the time yet after all this to test the port I/O and log it to a file with UNIMIX to see what the heck is going on for port mishmash yet.


I wonder if the mmpm2.ini has the connectors wrong... as in Phones Volume and Main Volume have got mixed.

Probably best to check what is what using unimix.exe before any attempt at changing the connectors around.

OK, I have everything else 'fixed' in this mess but the 'mis-directed' CD Audio output. It is still controlled by the PHONE slider in PMMixer. Of course! The wide audio output cable connection for the CD-ROM is (was) plugged into the TAD pin socket on the SBLive 5.1 card! And .. moving it from the TAD pin socket to the AUX socket does, in fact, transfer the audio input from the CD audio into the SBLive 5.1 via that 'channel'. Plus .. removing the four-pin cable from either of those SBLive 5.1 sockets results in no audio output from the CD-ROM. As anyone would expect if audio from the CD-ROM is coming through that cable.

Now .. why doesn't the audio from the CD-ROM come the way it is supposed to arrive to the SBLive 5.1 PCI card? I've got the little two pin cable properly connected between the CD-ROM and the SBLive 5.1 card socket.

If I run unimix -list > unimix.log and look at the file, I can see that:

Control ID 61 is the CD virtual mixer playback device
The value max is 1 and is set to 1 for both channels (R/L I guess)

Control ID 62 is the CD virtual mixer playback volume
The value max is 31 and is set to 31 for both channels (R/L I guess)

So .. my awareness level of how all this works is that the CD-ROM is expected to furnish audio to either the SBLive 5.1 through the IDE cable connections via the motherboard or via the two pin small cable connection between the CD-ROM and the SBLive 5.1 card. And .. isn't .. somehow. The Intel 915GAVL motherboard does not have any 'audio' input connection jack on it other than a 'front panel audio' jack. Which isn't CD-ROM oriented as far as my awareness goes.

And .. the Intel 915GAVL/GEVL motherboards do have built in audio support which at this point the Uniuudio tool set has partially working, with basic desktop sounds working, but no capability to handle through the desktop volume control or Unimix or PMMix tools. Thus the still required need for the SBLive 5.1 here.

I've absolutely now established that there is no IRQ fault issue or PCI address issue present between the still present Intel Comm Port 1 on IRQ4, the two PCI slot addition Comm Port 2/3 devices on IRQ3 .. and the fully functional PCI ActionTek modem on IRQ5. The PCI slot alignment is the SBLIve 5.1 on IRQ10 in slot 4, the needed Adaptec 29160 SCSI card in slot 3 on IRQ9, the PCI serial card on slot 2 on IRQ3 and the Actiontek modem in slot 1 on IRQ5.

The entire comm port complex and SBLive operation will function on either SIO 1.6 or SIO2K with the above. Although SIO 1.6 will only permit four comm ports to be used and since I need VMODEM on a port here if I run SIO 1.6 I can only use one of the available extra serial port devices on the two device PCI comm port add in card on IRQ3. Behavior of the audio operation is exactly the same and shows up exactly the same as to devices, port and IRQ traces with SYSINFO 8.2.5 on this box.


Can you (or anyone else here!) suggest how to proceed? Thanks!

Have you opened the system setup->multimedia setup->cd p3(click the plus)-> hardware volume levels->best guess is set? That should enable transfer of audio via the IDE cable.

Actually shouldn't the Digital Transfer box be ticked? (and why has the page numbers disapeared?)
