j313: convolver causes distortion/saturation at 100% volume level

[alxdrl]

Audio quality is degraded when volume is at 100% on my j313 (MBA 2020) compared to the listening experience under macOs.

As a reference, the piano chords in this tune at 0:53 are noticeably distorted.

• saturation remains when the bassex/bankstown node is bypassed in graph.json
• saturation reduced to an acceptable level when lowering the volume at ~80% level
• ditto when the convL/convR nodes are bypassed (while keeping bassex node)
• ditto when lowering the gain of the convL/convR nodes gain to ~0.6 (while keeping bassex node)

So maybe the IR is somehow off for j313.
