I was using for years a method for dowmix 5.1 to stereo using FFmpeg.
In particular the one called Downmixing without discarding the LFE channel (Dave_750's answer) and detailed in this post:

But since the last versions of FFmpeg, the option -vol has become deprecated.
So, in this example:
ffmpeg -i "signed16bitPCM.wav" -c pcm_s16le -vol 425 -af "pan=stereo|c0=0.5*c2+0.707*c0+0.707*c4+0.5*c3|c1=0.5*c2+0.707*c1+0.707*c5+0.5*c3" "Audio 4 (Dave750 Downmix).wav"
What to change the -vol 425 option to now?
Thank you very much in advance for your feedback ;)
