I don't have flac files so I cannot test it:

Code:

find -iname '*.mp3' -exec bash -c "
  id3 -Rl \"\$@\" | 
    awk -F: '
      /(t(itle|rack)|a(rtist|lbum)):[ \t]*((unknown|track)|[ \t]*)\012/{
        print \$2
        }' IGNORECASE=1 RS=        
  " {} + -o \
  -iname '*.flac' -exec bash -c "
    metaflac --export-tags-to=- \"\$@\" |
      awk -F= '
      /(t(itle|rack)|a(rtist|lbum)):[ \t]*\012/ {
        print \$2
        }' IGNORECASE=1 RS=     
  " {} +

Seem to work for me for mp3 files.

Consider that if you want the file to be printed in case id3 or metaflac return no output at all, the entire flow should be modified to process one file at a time and that change will have dramatic performance impact (you should decide which one is more important: functionality or speed).

NAME

       ossdevlinks - Open Sound System legacy device management utility.

SYNOPSIS

       ossdevlinks [-vr]

DESCRIPTION

       The ossdevlinks utility creates and manages old style (legacy) device files for OSS audio, MIDI and mixer devices.

       In  previous versioms OSS used "flat" device numbering for the device files (for example /dev/dsp0 to /dev/dspN). OSS version 4.0 and later
       uses different naming scheme. The ossdevlinks utility is used to manage the legacy device names as symbolic links to the new style devices.

OPTIONS

       Normally ossdevlinks is used without command line arguments. However there are a few command line options.

       -f<name>
	      Write legacydev file to <fname>.

       -N     Do not actually modify device files

       -r     Reset the legacy device numbering (do not use).

       -v     Verbose output

       The -r option may invalidate audio device selections in the setup files of various applications. This  is  considered  highly  undesirable.
       Applications using wrong audio devices may cause serious security and privacy problems.	For this reason the -r option should never be used
       unless there are no other ways to recover from serious audio/sound related problems. After that users should review the audio  settings	of
       all the audio applications they are using.
