Missing Audio Sample Rate

Has anyone ever seen this before? I have a single disk out a set of six where one of the audio tracks (Japanese) doesn't have a sample rate set for it.

MakeMKV doesn't even list the track as an option, and additionally it takes much longer to query the disc for the available titles then other discs I have used. And when ripping what it does see it takes a long time, and usually has one or two titles that won't convert.

I've attached some logs from ffprobe to illustrate the issue.

The interesting part is this, stream #0:3 has no sample rate like the others. #0:1 and #0:2 do.

Code: Select all

Stream #0:0[0x1011]: Video: h264 (High) (HDMV / 0x564D4448), yuv420p(progressive), 1920x1080 [SAR 1:1 DAR 16:9], 23.98 fps, 23.98 tbr, 90k tbn
Stream #0:1[0x1100]: Audio: truehd (AC-3 / 0x332D4341), [b]48000 Hz[/b], 5.1(side), s32 (24 bit)
Stream #0:2[0x1100]: Audio: ac3 (AC-3 / 0x332D4341), [b]48000 Hz[/b], 5.1(side), fltp, 448 kb/s
Stream #0:3[0x1101]: Audio: ac3 (AC-3 / 0x332D4341), stereo, fltp
Stream #0:4[0x1200]: Subtitle: hdmv_pgs_subtitle ([144][0][0][0] / 0x0090), 1920x1080
Stream #0:5[0x1201]: Subtitle: hdmv_pgs_subtitle ([144][0][0][0] / 0x0090)
Any thoughts?

I can get logs from MakeMKV as well.
