Arduino Giga R1 3.5 audio output not stereo

Hi everybody. Is there someone here with reliable informations about the mono or stereo operation, of the 3.5 jack Giga R1 audio output?

I am using a wavetable synth sketch from the Project Hub, and I'm finding that the audio output is unexpectedly from left channel only.

I know that the Giga board has two DACS of analogue output line, thus I implicitly surmised that the signal should be stereo, or at least an L-R cloned mono a-la Nord Lead 1/2.

I do not happen to have found any specific details in the Giga documentation, about the TS (mono) or TRS (stereo) native functionality of the output audio jack.

Any advice appreciated!

The schematic shows this:

IDK how reliable that schematic is, and I don't have an Arduino Giga to check it any further.

I have deleted your other cross-post @zaphyrclouder.

Cross-posting is against the Arduino forum rules. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend a lot of time investigating and writing a detailed answer on one topic, without knowing that someone else already did the same in the other topic.

Repeated cross-posting can result in a suspension from the forum.

In the future, please only create one topic for each distinct subject matter. This is basic forum etiquette, as explained in the "How to get the best out of this forum" guide. It contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

No problem at all: I do appreciate that cross-posting might waste someone's time that could be better invested elsewhere. Anyway, it was unintended, since I wasn't sure as to where properly/effectively pose my question.

Sorry for any possible and yet totally unwilling infringement of local netiquette.

@Dave_Lowther thanks for your documentation. Going from what I see in the attached image, it definitely seems that the joint output of the two Giga DACs is meant to work as a L+R stereo image. I will therefore investigate further my issue, maybe (but hopefully not) depending on the wavetable synth sketch implementation.

Regards.
