How common is it in games these days to have 5.1 (or similar) multi-track uncompressed audio tracks?

Is it not at all common or rare? (Usually, mono/stereo audio files occur in games.) A rough example of this in terms of volume is the game Titanfall, with its nearly 35GB of uncompressed audio.

The question would be interesting because according to the statements on the "HydrogenAudio" forum, for multi-channel audio tracks, the TAK codec is much better than FLAC and the like. Does anyone have any experience with compression with this?

Similarly to compressed audio, BINK2 is still the most common video codec, and in the case of games released in the current decade, is it starting to gain ground instead, with videos encoded with x264/x265? (In the case of x264, one could technically talk about lossless recompression, like BPK does with Bink1/2 files.)
