I'll try to provide some useful signs/symptoms of the
particular difficulty. The principal message I get is:
--start snip--
bob@debian:~$ mount /dev/sr0
mount: /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on
/dev/sr0, missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
--stop snip--
Following the above suggestion:
--start-snip--
bob@debian:~$ dmesg |tail

You can see where, on the last line, I tried monkeying
with sr0's options. I've left the file now as it was
installed by jessie, which flavor I am still running,
albeit sans (without) systemd. I have tried three
different audio cd's.
Humbly and respectfully submitted for the amusement and
edification of the assembled faithful, and Gene.
Thanks,
