By no means scientific, but here are a couple things I found

At about 8:20 there are some military escorted press phtographers, and the frogs chirping are similar, but in footage at 2:00 or so there are flows at expected speed, and with more ‘lava noise’ as one might expect.
Also, here:

with more footage of lava rivers and apparently the correct ambient noise. Part way throgh there is not a river but near a rift with very loud and impressive noise.
I realize not the same situation, but still with the lava being thrown up in the air, might be somewhat similar.
