2 years ago I never use the earphones: The simple solution would be to use the VolumeControl which is available in the Framework. This will impact both the speakers and the jack.
If you look for a challenging solution you might dig into the ES8388 Datasheet...
But first you might want to try the AI_THINKER_ES8388_VOLUME_HACK setting, which seems to control the volume on both output channels.

2 years ago Thank you Mr. S! Since I am a software novice, looking at the volumestream example you linked I am struggling to apply it to the two example code below one of which which is a modified version of one of your other examples.
Could you help? My issue is would it apply to "kit" and where in the flow.
Thank you very much!!!

2 years ago Oh, there is not need if you use the player! It has the volume control already included: Just call setVolume() on the player!

2 years ago As you can see in my example I try both kit and player volume control. The adjust speaker outputs but not earphone out volume.

2 years ago I guarantee that if you set player.setVolume(0.0); you won't have any audio on the earphones! By the way you should not use both or you get very confusing results. Keep the kit volume at a constant value!
Are you really testing with earphones and not with a device which has automatic gain control and automatically amplifies a weak signal ?

2 years ago Hi Mr. S,
Thanks again for staying with me!
I tested more and in fact as you said player volume control is modulating volume on earphone out. I still have a problem though.
The reason I didn't realize this is I had (2) 3W speakers plugged direct into board and at the same time had earphone out plugged into a 2x20 lepy amplifier (LP-2020A) into (2) 50W speakers with volume on knob on amplifier turned fairly high.
When player volume is adjusted to .9 the 3W speakers when up and I expected the 2x20W amplifer to be blaring but wasnt. In fact the 3W speakers dwarfed the sound from the 2x20W amplifier so I couldn't tell that in reality the big speakers and amp are moduling volume its just so low it could not be heard.
If I disconnect the 3W speakers and leave only the earphone out to the amp with amp volume at full....I can hear an output on 20W amp at full knob turn but its light/. Much less volume than the 3W even though Amp is at full.
Seems like while earphone out is modulated its volume overall is very very low. So low the big amp cant get the signal louder than what the 3W speakers can get to with on board DACs
I am not sure how to set registers is ES8388 SoC but I think I see some registers I might want to set.
Earphone out not really usable at these levels.
Knowing player is modulating volume but a very low volume do you have any other ideas?
Thanks again!

2 years ago Did you try to set both the player and kit to max volume (1.0) if you get an acceptable volume out of your amplifier ?
I tend to think that this is rather an issue of your amplifier. I can double check this tomorrow with my amplifier but I am pretty sure that there will not be any problem if I use Aux In. You can double check this on your side with some earphones which I am certain will be very loud.
Unfortunately the registers will not help, because you can only attenuate!

2 years ago I just plugged in passive earphones...so faint you cant hardly hear. While if I plug in 3W speakers very loud.
earphone jack is very low best I can tell, even with power 2x20W amp out of test.

2 years ago Strange, mine are very noisy - Did you try the AI_THINKER_ES8388_VOLUME_HACK in the AudioKitSettings.h ?

2 years ago Yes, it worked!! Thank you very much!
Apologies! I feel I should have seen that in setting h file.

Mr S!
Love your work! Thank you!
One question, I am wondering if I am using something incorrectly or there is functionality not yet completed.
I am using aithinker audiokit board.
All the example sketches work for me in audiotools and in audiokit github repositories.
I am noticing a volume control issue with the earphone output. I have 2 speaker configurations, one using a small set of speakers plugged directly into on board speaker jacks and the other I am running into a set of amplified speakers from earphone output jack .
In the example, streams-audiokit-sd-audiokit
when I connect speakers to onboard ports, the line kit.setVolume(0.9); controls volume from mute to fairly high volume by 0 to 1 setting in argument.
However, when I connect amplified speakers to the earphone out 3.5 mm jack, this setting doesn't seem to control the earphone out volume and it remains very low.
I would like to be able to get volume control on 3.5mm earphone out jack in a similar manner to the control I have of the onboard speaker jacks.
Do you have any suggestions?
Thanks,
Chris
