You mount a file system. Audio CDs (that is, CD-DA disks) do not hold file systems, so they aren't mounted in the typical sense. Note that while CD-DA disks are technically CD-ROM disks (compact disk read only media), in typical usage "CD-ROM" is taken to mean a CD which contains _data organized as files within a file system_, often an ISO-9660 file system typically with extensions (Rockridge, Juliet, ...). > I wanted to use aplay to play music on cdrom, but have concluded > it cannot be done in any straightforward way. Why not? Likely simply because nobody has implemented that. Software to play audio CDs exists aplenty; is there any particular reason why you want to use specifically aplay to do it? > However, about every 15 seconds the the > process stops for about one second ane the drive LED flashes on. I suspect this is because of insufficient read-ahead or insufficient bandwidth, as you seems to assume to based on your comment on buffer size. You might be able to use --cache=yes to improve matters. Another option is to copy the CD audio to the computer using some tool designed for that, and then play the copy. I suggest trying cdparanoia for this, as it has excellent handling of poor read quality or buffer underrun/overrun. > To simplify my life, I created a ~/scripts/play file. It is in my > PATH.

Check the output of: type play Most likely something else named play comes earlier in your $PATH. -- Michael Kjörling 🔗 https://michael.kjorling.se “Remember when, on the Internet, nobody cared that you were a dog?”
