That's correct, ffplay *never* supported a -vol option, maybe you're
confusing with the ffmpeg option.

Wait for audio filtering, but yes you're welcome to file a feature
ffmpeg-user random tip #3
Some few multimedia formats (mpeg-1, mpeg-2:PS, DV) support physical merge
consistency, which means you can merge two files with cat. E.g.:
cat input1.mpeg input2.mpeg > output.mpeg
