It imports quite fine using Audacity -> File -> Import Raw( with these specs: Signed 32 bit Little Endian, Rate 192000 Hz, Stereo, ) I just find it strange that every 2 words always is 0x0000 and the opposite 2 words of the same long word contains data.
This however does not explain why there is 16 bits of data within the 32 bits available, when there should be 24 bits spent out of those 32. According to: /proc/asound/card2/stream0 Format: S32_LE, Channels: 2, Rates: 44100, 48000, 88200, 96000, 176400, 192000, Bits: 24
In other words I would expect some data where I put the Xs in the below example; or byte swapped? as BE and LE are no longer part of my active vocabulary: XX00 or 00XX
Code:
00508970: 00XX 49f3 00XX fdf2 00XX c7f2 00XX 7cf2 ................
