Audio CDs play by a different route to all other sounds on your PC. The sound is piped directly from the drive to the card without passing through the CPU. So, you need to have this audio cable in pace.
That's not entirely true. Most newer CD drives support Digital Audio Extraction (DAE -- what's required for ripping) and hence can play through the system's digital audio circuitry, which does, of course, involve some CPU involvement, though often not a lot, since 16-bit, linear PCM at 44.1 Kilosamples per second (a.k.a. CDDA -- Compact Disc Digital Audio) is a pretty digital audio format that is widely supported by desktop audio hardware. It seems the defaults have been switching from analog audio as you describe it, direct from player to audio card, to digital, processor-mediated playback.
Indeed, even this might not be enough - my system is set up properly but I cannot play CDs directly.
I do believe this worked under 9.0.
Are you sure? If so, perhaps something's come loose inside the case.
Alternatively, there are CD players that will stream the music off the CD through the system and play that streamed music (rather than playing the audio CD directly). However, I'm not sure which players will do this - I have simply ripped all my CDs onto my hard disc :-)
As I mentioned above, if you can rip from a given drive, then you can perform digital playback. Some (most? all?) playback software offers the option to choose either digital or analog playback.
