You're right - this was exactly the problem, resulting in setting of
amplification to 0 as Sean also suggested. Thank you both!

Interestingly, I  happened to see that 'lame' element includes a built-in
low-pass filter set via the property "lowpass-freq" so it looks like I don't
have to use the audiocheblimit element after all.

Is the main difference between 'audioamplify' and 'volume' the clipping

Thanks again!
