From qemu's manpage:

       -audio-help
           Will show the -audiodev equivalent of the currently specified
           (deprecated) environment variables.

$ qemu-system-x86_64 -audio-help
Environment variable based configuration deprecated.
Please use the new -audiodev option.

Equivalent -audiodev to your current environment variables:
(Since you didn't specify QEMU_AUDIO_DRV, I'll list all possibilities)
-audiodev id=pa,driver=pa
-audiodev id=alsa,driver=alsa
-audiodev id=oss,driver=oss
-audiodev id=none,driver=none
