Need help with audio extraction

I am trying to extract audio from VOB files ripped from a DVD to my computer. VLC shows that there are 5 streams, 2 of which are audio. Stream 3 is A52 (AC3) 48kHz 256 kbit and stream 5 is PCM 96kHz 24 bits per sample. The video and audio play correctly in VLC, but I can't figure out how to determine (or select) which audio stream is being played. Avidemux plays the video correctly, but its audio output is just sputtering noise. I wish to extract the 96/24 audio to WAV. As expected, the WAV file output by Avidemux contains the same sputtering noise. Looking at it in an audio editor, I see a repeating pattern of about 60 msec of random noise followed by 40 msec of silence. Is this DVD format not supported by Avidemux, or am I doing something wrong? Thanks in advance for any help.

Update: I have found that Avidemux 2.6.21 64 bit crashes when attempting to play over half of downloaded VOB files. Is Windows 10 not supported?

Unfortunately, 24 bits audio is not supported in Avidemux. I wonder if mpv

mpv --no-video --aid=1 --ao=pcm --ao-pcm-file=path/to/audio.wav

might work.
