Alltogether around 30 so far.
Oh, it doesn't have to do with the number. When I'm assembling units, I am combining the same types.
So from order numbers 23 - 50 (which is what I'm currently assembling), I first count what I need and then assemble the units accordingly.
Some might've wondered why not all units I planned to ship until yesterday have shipped yet - and some followed IRC or our Discord channel and could imagine what the reason was.
During assembly, I noticed that about 10% of the units didn't want to boot up after they had been powered down.
This can be related to some weird audio mixing / channel mapping.
I already mentioned to aTc during the tester that it sounds as if the audio is coming from both speakers whenever I only play from the left one (as I'm sine waves for testing, this could've been my imagination and I've not further...
Yes, that can be the issue. The volume daemon is very simple at the moment and needs optimization (deadzone, polling, handling ALSA / PulseAudio, etc.... I'll post more about that.
That's why I mentioned to open AlsaMixer. If the volume wheel is the issue, you will see the AlsaMixer slider moving :)
Oh. And I remember there's some low-power mode for the audio stream.
It can be enabled / disabled in Alsamixer as well (it's that hpll or similar controller, forgot the name).
Maybe that can cause such issues.
I'll also try on the units I have here.
Hm, interesting. Please check the following:
1. Test if volume changes if you press on the case (not a key). The speakers use spring contacts - maybe they don't have a proper contact on your unit (which changes if you press on the case).
2. Open Alsamixer to see if the volume actually changes.
AAhh, well, power supplies can indeed cause such effects.
What actually causes such "whining" is usually vibrating capacitors. If they hit the resonance frequency of the PCB, the PCB starts to vibrate which turns into the noise you can hear.
Power Supplies (especially cheaper ones) can cause...
That is pretty cool! Actually, could this be changed easily to work with the GameBoy Color?
McWill's LCD Mod includes a charging mod as well - however, it does not replace the full power circuit of the GBC, which is pretty flakey.
My own unit doesn't start anymore when I add the Charging mod and...
It will work but I'll just cancel and refund the second one :)
1. If you pre-ordered both at the same time, you can get both.
2. Yes, as long as not too many do that (due to failure rates, I need to order more boards than I need anyways, so a few changes are no issues).
