Yes - I played around with this quite a bit a few months back - I
did get something working reasonably well, but the details are a bit
hazy for me now...

There is something buried deep in the ViaVoice docs about
changing this in some respects ... but I think I just used sox
sox name.au name.cdr

I had this problem when I was trying to do an mp3 format CD (the
player was quite limited in what mp3 parameters it could handle)
- but I guess you were only trying to do plain audio?
In that case the problem may be with the vintage of the player?
Old players (c 3 years+) will have problems with CD-R and (even
more so) with CD-RW media. I have several players of that sort.
Were you able to play on the drive on which you did the recording
(obviously, *it* should be compatible...).

Hmmm ... doesn't sound right (excuse the pun!). CD format data
files would more typically have a .cdr extension - see my sox
I just used:
cdrecord -v blank=fast
to first blank, and then:
cdrecord -v -audio *.cdr
I have a bundle of scripts and stuff that you are welcome to if
you want to play with them - no docs, do warranties, but you're
welcome to them. Includes a little script to chop a long .wav
into shorter fixed time segments so that the CD can be more
conveniently navigated by track...
