I'm currently using CRDWIN to convert my psx games into .bin format to play with ePSXe.
The problem is I dont seem to be able to get any CD audio when i do this.... so I was wondering if this is normal or is there a setting for this?
Thanks
Rob

For CD audio to play you have to have an analog cord attached from your CD-ROM drive to your soundcard. Therefore, you can see the problem that lies in ISOs (there is no actual CD-ROM to connect) and CD audio. I'd suggest playing those games with the actual CD if you want to hear the music. To the best of my knowledge there is no workaround to this.

Music works fine from isos when I make em using cdrwin.. Most psx games nowadays don't use regular cd audio for music.. Hence, no need for the analog cord.. Its just all data.. Why would you need the analog cord to have music working in an iso? An iso is running off your harddrive, not your cd rom..

Yes, there are only a handful of PSX games that use redbook audio but I think the game that he's referring to is one of them. Midi and XA tracks should play using an ISO.

CD audio MUST have the analog cord in order to output. It's designed to channel directly into the soundcard. And an analog cord isn't necessary for running off an ISO, it's just there's no way to connect the audio cord to the ISO (it's an image; there's no CD-ROM drive) so hence, CD audio in an ISO will not output.

This may be true for the current ver of epsxe (1.4.0) but is it possible to read audio tracks form an iso and pass it through the souncard as a pcm or wav signal? perhaps in the next version?
Games like tombraider 1 and 2 really need this feature as without the background music they seem a bit dead?

Thanks for the info guys :)
But im still none the wiser... I have a soundblaster live so should this get CD audio off an ISO? And when copying into ISO format I use raw mode
thanks

Perhaps I can explain.

The problem currently is that the ISO driver is unable to virtualize redbook audio.

Under normal circumstances, when the PSX (and thus the PSX emulator), calls for a CD audio track, it leaves it to the player to start playing a track just like you would any audio CD player.

You can hear CD Audio from CDs if you have some means of routing the sound from the drive to the computer. Most often that means a 4-pin analog sound connection to your sound card, but most modern drives can also send out the data digitally (via a 2-pin connection) for crisper sound. The trick is you need a sound card capable of receiving that data.

Back to ISOs. The ISO driver is currently unable to interpret a "play track" command. There are two reasons for this.

First is that the ISO driver currently doesn't look for the CUE. The BIN file is only half of the equation: it's just the raw data. The CUE tells burners what is what, and the ISO driver will need that file to tell just what part of the BIN is an audio track.

Second is that the ISO driver currently lacks a CD Audio virtualizer. Once the driver is capable of interpreting CUEs, it must also be able to read the sound data, convert it to some playabale format, and then route the PCM data on to the sound card. Such a virtualizer will require some work because of its independent nature, but in general, those are the two reasons ISOs don't play redbook.

I don't think ePSXe can actually make use of a digital lead. It's the only one I have between my CD-ROM and my soundcard (I lost my analog one.. ggh) and I can't get CDDA playing anymore.
