No. Audio CD's are played by turning your CD-ROM reader into a "dumb" player. The CD Reader itself engages and plays back the Audio CD.
Output takes the form of either (or both) a DIGITAL, or ANALOG signal coming from the back of the CD-ROM reader. This signal is fed to the sound card via a separate cable. If your CD-ROM reader and audio cards are SPIF capable, you actually might have two separate small audio cables running from the player to the sound card. One is an Analog cable, the other provides digital output. When CD's are played back the audio signal feeds into the sound card's on board mixer and then goes out to the speakers. This circumvents the CPU altogether, placing almost no load on the computer. If you powered your CD-ROM reader directly you actually wouldn't even need the computer. Certain Rippers on the other hand can grab the digital data directly from the audio cd. They do this by utilizing code that can interpret the audio data as a file system. The computer then can copy the audio data to the hard drive (or software) without passing thru the sound card at all, or undergoing D/A,A/D conversion. The resulting MP3 files that the rippers create can be listened to on your computer via software that directly feeds the sound card's D/A converter. Thus you can have a CD-ROM reader which may be missing it's audio cables, yet you can still digitally "rip" your audio music to MP3 files. You can also play those files back without problems and hear them fine. However if you insert an audio CD into the player and attempt to play it directly, you hear nothing, since the feed cables are missing. -JMS |-----Original Message----- |From: [EMAIL PROTECTED] |[mailto:[EMAIL PROTECTED]] On Behalf Of Jesus Arocho |Sent: Thursday, November 08, 2001 6:35 AM |To: [EMAIL PROTECTED] |Subject: Re: [expert] 2.4.13-2 & NVIDIA | | |On Thursday 08 November 2001 00:52, you wrote: |> Has cdrom sound worked in the past?
