Re: sound from CD-ROM



From: stevens @ elab.columbia.edu (Andy Stevens) @ INET

well, I went out and bought one of those Panasonic PCMCIA CD-ROM
drives.  The setup was real easy, and I am now able to run CD-ROM
software.  However, I can't seem to get the thing to play any sounds
through my TP750C audio chip.  Is this supported?  As per Panasonic's
suggestion, I installed "[MCI] CD Audio" in my windows, to no avail.

Andy--

You can't play audio internally on a PCMCIA CD ROM drive.  The internal data is 
digital information on a digital signal.  CD Audio is digital information on an 
analog signal (that little 4-wire cable that runs from internal CD ROMs to 
sound cards).  You'll only get audio from the headphone jack or an auxiliary 
output on the CD ROM drive.  The headphone jack will be amplified, so if you 
want to run a cable from there to an audio input, as someone suggested, you'll 
have to turn the volume on the drive almost all the way down & use the software 
volume control only (you may still lose some sound quality).  If your CD ROM 
drive has an auxiliary output, it will not be amplified & can go to any 
amplifier, ie. a stereo,  your Thinkpad's audio input jack, or amplified 
speakers.  In any case you can still use CD Audio software to make it spin.  If 
you get no response from the software, ie. Windows Media Player doesn't give 
you a CD Audio option, remove the CD Audio driver from Control Panel, restart 
Windows & then reinstall the CD Audio driver with a CD in the drive.

Sorry this response is late coming.  I haven't had the time to look at the list 
this week.
