I have had an issue arise that maybe someone can help with. I have setup SOX resampling to selectively resample to 384 but adhere to the base frequency. This works for 44.1, resampling to 352 but on 48 base data it still indicates 352 rather than the correct 384 when I check Audio Info. Is this what is actually happening or is it a reporting error?
Can it be corrected?

Do you perhaps happen to have one of those DACs that can report the sample rate they are getting?
It could be a bug in SOX, although I doubt. It could also be a miscalculation in moOde's Audio-info page. The DAC, though, will definitely tell us the truth.

It is the ProtoDac. I have no idea about what it can report but would guess that it has no such capability.
Thanks!

Yes, I see now.
Well, to be sure SOX acts correctly the only thing I can think of is one of us setting up the resampling as you did, and check how things go with the two base-frequencies.
I've never done such a thing, but maybe later today I can try. My DAC reports on its screen what is being fed with, so the check will be quick to do.

A quick test and I'm not seeing this issue.
The ProtoDAC is on top of an Allo Kali Reclocker.

Try without the FifoPiMa
I will try next time I have it apart. Till then I posted a screenshot of audio info, I will try sample to 192 and see if that works.

Try w/o polarity inversion and then if no change turn off the custom SoX settings and retry.

No change with either phase inversion settings or non custom recipe. But A192 seems to work. If i switch back to 384 the next play works but only 1 play! After that it reverts to 352.
Very odd.
In Audio Config what I2S selection (driver) are you using?
The ProtoDAC w/o reclocker or with a reclocker like Allo Kali or FifoPi Qx should use the i2s-dac (passive mode) driver. This is automatically assigned when selecting "ProtoDAC TDA1387 X8" from the I2s dropdown.
For the FifoPiMa recliocker the hifiberry-dacplus (master mode) driver should be used. This is automatically assigned when selecting "ProtoDAC TDA1387 X8 (FifoPiMa)" from the I2s dropdown.
