Thank you for the replies, @uli and @Dmian.
I'm using an Orange Pi Lite V1.1. Firmware revision is v0.90-177. Imaging software used: Etcher and Win32DiskImager, both using the inbuilt card reader and external card reader on a Dell E7450 laptop, as well as a Dell G3 3500 laptop.
My config file (after changing the default beep volume to 15 to see if they rectified the issue):
keyboard=1
mode=1
font=2
keyword_sep_optional=0
language=0
filter=0
cursor_color=0xff009500
beep_volume=15
phys_mode=0
tv_norm=0
color0=0,0,0
color1=192,192,192
color2=255,255,255
color3=128,128,128
color4=10,120,160
color5=140,140,140
color6=244,233,123
color7=214,91,189
color8=50,50,255
color9=238,137,17
color10=84,255,0
color11=0,0,0
Trying SAY "Hello, world!", BEEP 15, PLAY "A1B1C1", or playing SHMUP yields no sound output over HDMI (I've since tried it on a couple more televisions).
I've since tried the three latest firmware builds, using a large number of configurations, to no avail (used both Etcher and Win32DiskImager on a Dell E7450 & Dell G3 3500 laptops - both using inbuilt and external card readers). I'm not good at soldering, nor am I averse to it either, but these soldering pads are at the upper limit of my finite soldering skills 🙂 Unfortunately, I do not have a 3.5MM audio pigtail, so I will have to order some in from Amazon. While I am there, I will see which other Orange Pi are available from stock within the United States and order one with an existing audio jack - if possible 🙂
Thanks again for developing this awesome little setup and for your help!!

Edit #2: Sleep deprivation is a nasty thing. I started reading through more threads and see there is a HELP command ( and assuming as much after seeing the json help files in the sys folder). I will try to go through them and document it as I go. It may even lead to a cure to the problem in the topic....or maybe I've got a lemon - that isn't terribly uncommon from what I've read this evening. In any case, I've ordered some 3.5MM audio jack pigtails, an Orange Pi PC for when I inevitably screw up the Orange Pi Lite soldering on it (I have mild essential tremors), and a high quality high output multi-port USB charger (something to power the OPI BE, original BE, Color Maximite, and Color Maximite 2...hopefully).
