Bounce to .wav / cd goes bad

After many years of smooth operation the .wav I burnt on an audio cd can't be played on any audio device, except on my iMac.

It is a standard audio cd, and bouncing as always .wav.

But now the cd identifies as 'Nameless', while before this problem it identified as 'audio'.

Thanks for your help.
