Here is what it says there:
-a <params>
Specify parameters used when opening an audio output device. For ALSA, the format
<b>:<p>:<f>:<m> is used where <b> is the buffer time in milliseconds (values less
than 500) or size in bytes (default 40ms); <p> is the period count (values less
than 50) or size in bytes (default 4 periods); <f> is the sample format (possible
values: 16, 24, 24_3 or 32); <m> is whether to use mmap (possible values: 0 or 1).
For PortAudio, the value is simply the target latency in milliseconds. When the
output is sent to standard output, the value can be 16, 24 or 32, which denotes the
sample size in bits.So how would I put that in the „ALSA Parameter“ part under „Audioplayer“ I did a „a b32“ to say buffer time 32 in size. But I don’t think that is the right way to do it. They should show some examples on that man page.

I wanted to test this out on my Pi 4 with 4GB RAM.
It works and I hooked it up to a blue tooth speaker and worked real good.
Went to bed and got up the next morning and went to play some music with it but it did not.
Said to connect to the blue tooth and it say’s connected and in about 3 sec. Say’s disconnected.
I did this like 10 times. Turn off and on the blue tooth and right away says connected then disconnected right after that.
Did all I could think of removed it and connected it again. Just did not reboot the Pi 4 I guess should do that.
Here is some info copy and past from it.

You can open this and unsolder the 3 wires to the battery. Then just solder the + and – on it can use a 5 volt USB cable with the ends cut off.
I used a flat tool from this set:
Tech Rescue Kit (46-Piece). You can see it at https://www.tekton.com/everybit-tech-rescue-kit-28301.
In the photo of it the top tool under the red pointer I used. On the sides between it and the back and put that took in and push down the back just snaps in.
I had this up for over 10 days all ready. Just power with a power 5 volt power supply.
Junk they don’t make it have OTG On The Go power. I can plug that cable in and use a none power USB hub and it powers a USB to Ethernet and keyboard and mouse. The keyboard is a lighted keyboard have on it too. Just need a good amp 5 volt power supply.
The back has a sticker over the hold at the bottom a black one with words on it. When got the back off and just push it off and I stuck it on another part of the back and ran the wires out that hole the black sticker was covering up.
Here is a good photo on there webpage of that tool
In Linux or Ubuntu it shows the battery going down over time but it don’t turn off when it goes to 0 like some cell phones do if you power them like this.
It will say up as long as you got power to it but it will think the battery goes down to 10% and looks like will not go lower then that. If with time it thinks it goes down you can not do a reboot. Have to turn off and on the power and it starts thinking the battery is 100% then. But slowly goes down but like I said it don’t turn off.

About the LCD screen brightness. At lest the 7 inch touch one I have.
Went to try and test dimming it but so I went to this web site. Went to the folder /sys/class/backlight and did a git clone https://github.com/linusg/rpi-backlight.git because that folder is not there. But it says Permission denied and I log in as root. I guess it’s not a real root or I just don’t know why.
I was going to take the SD card out and mount it in another Ubuntu. But it’s to hard I would have to open up this hole case to get the SD card out.
If could do the dimming on the command line there are other web sites that say how to install a light sensor.
Tested tying it another way but it don’t work ether.

O so if you have it on „Auto“ then it’s just like normal then right? So it turns off the the shutdown button right?
But were does the „auto“ wire goes. Were do you put that wire. It just ends nothing is there on the schematic.
All so is the On/Off button stays on just a little time or does it stay on or off. So if you press the button does it keep the a continuation or not? So what type button is it. So is if a Momentary or toggle switch? The schematic just says On/Off so hard to know. I guess that means it is a toggle switch.

I got it to auto start Squeezelite and work on boot by putting this in /opt/max2play/custom_autostart.sh The hole file looks like this now.
#!/bin/bash #Custom Autostart File #Start squeezelite so Max2Play works on NanoPi NEO Air with NanoHat PCM5102A sudo -u root -H -s squeezelite -o hw:CARD=Pcm5102a,DEV=0 > /dev/null 2>&1 &Rebooted it and went to it’s web page and says Status: Squeezelite is running with processID 1175 Your processID will be some other number.
All problems that I know of fix on this now!

From what I remember just downloaded a image for it 1st and put that on a SD card and set it up so I could log in to it and updated it.
Then did the commands to install Max2Play.
Can find images for the NanoPi Neo Air here.
I still have to run a „squeezelite -o hw:CARD=Pcm5102a,DEV=0“ on the command line to get it to play music with Logitech Media Server. It will say then that Status: Squeezelite is running with processID XXXX
I can try all the soundcard Select Audio output it list and start but it still don’t run! Just have to do that command on the command line and then in Max2play web page it says its running.
