Audio sample rates on DV tape - vegascreativesoftware.info
https://www.vegascreativesoftware.info/us/forum/audio-sample-rates-on-dv-tape--38975/
The DV standard is for 32KHz audio to be sampled with 12 bits resolution, but what I think is happening is that when this is saved on the hard disk (either as AVI or WAV file), an addiitonal 4 bits of padding is added so that the data is stored in 16 bit words. This would be much easier for most applications to work with.

DV, originally known as DVC (Digital Video Cassette), uses a 1/4 inch (6.35mm) metal evaporate tape to record very high quality digital video. The video is sampled at the same rate as D-1, D-5, or Digital Betacam video — 720 pixels per scanline — although the color information is sampled at half the D-1 rate: 4:1:1 in 525-line (NTSC), and 4:2:0 in 625-line …

DV video information is carried in a nominal 25 megabit per second (Mbits/sec) data stream. Once you add in audio, subcode (including timecode), Insert and Track Information (ITI), and error correction, the total data stream comes to about 29 Mbits/sec or 3.6 MBytes/sec. Roger Jennings' papers run through the detailed numbers.

For instance, it’s the standard sample rate in audio for video. This sample rate moves the Nyquist frequency to around 24 kHz, giving further buffer room before filtering is needed. Some engineers choose to work in even higher audio sample rates, which tend to be multiples of either 44.1 kHz or 48 kHz.
DVD-Audio - Wikipedia

The maximum permissible total bit rate is 9.6 Megabits per second. Channel/resolution combinations that would exceed this need to be compressed. In uncompressed modes, it is possible to get up to 96/16 or 48/24 in 5.1, and 192/24 in stereo. To store 5.1 tracks in 88.2/20, 88.2/24, 96/20 or 96/24 MLP encoding is mandatory.

Nyquist’s Theorem. According to Nyquist’s Theorem, for an accurate digital representation of a sound wave, the sample rate must be, at least, two times bigger than the highest frequency going to be recorded.As the highest sound a human can hear has a frequency of 20 kHz, the minimum sample rate must be 40 kHz to be possible to digitalize this frequency.
Typical movie audio bitrate of DVD (192k??) - VideoHelp Forum
https://forum.videohelp.com/threads/378392-Typical-movie-audio-bitrate-of-DVD-(192k-)
Not sure what is typical ( most-used audio bitrate for plain ol' DVD). Thx for any insight you may provide! 192 is typical for stereo. DD5.1 is usually 448. Yes, typically AC-3 (Dolby Digital) is 192kbps for 2.0 and either 384kbps or 448kbps for 5.1. Some DVDs also have DTS 5.1 which I've found is either 1,509kbps or 755kbps.
