unable to add filter:a to ffplay

Im working on a video editing project and im using ffmpeg for video rendering

To play video before rendering i wana show it to user and i thought of using ffplay

ffplay -i C:/Users/thota/OneDrive/Desktop/VET/test.mp4 -filter:a "volume="1.0",atempo="1.0"" -vf "transpose=2,transpose=2,setpts=1/"1.0"*PTS,scale="1280*720"" -aspect 16:9 D:/videos.mp4output.mp4

but this is giving an error:

Failed to set value 'volume=1.0,atempo=1.0' for option 'filter:a': Option not found

ffplay only recognizes -vf/-af for video and audio filters respectively.

-af "volume=1.0,atempo=1.0"
