HDCD CDs and transcoding

It states

When using the filter with wav, note the default encoding for wav is 16-bit, so the resulting 20-bit stream will be truncated back to 16-bit. Use something like -acodec pcm_s24le after the filter to get 24-bit PCM output.

So

Code:

-af hdcd

becomes

Code:

-af hdcd -c:a pcm_s24le

Of course, this could simply be another way of specifying wav:L24;

BTW I already tried wav:L24 and my renderer played "pink noise".
Same effect with -c:a pcm_s24le option. Please note my rendered cannot handle wav format. Si I will have to convert to lpcm.
