No HDMI audio

uli

I have looked into it again, and it seems to me that the lib-h3 driver does not do any HDMI audio initialization at all, with the exception of turning on the clock. If that is true, it's a miracle that sound worked for anyone at all...

I have reinstated the HDMI audio initialization code from the old driver; please check out the latest build and see if that helped with your issue. Thanks.

Wow, that was fast uli !
OK, having sound despite audio not being initialized definitely sound's like miracle to me^^
Mhhh, but it seems there is more to it than just reinstating HDMI audio initialization. Just tried out v0.90-285 (with default config).....and sound is no more again. Damn!
This couldn't be a problem specific to the Lite-Model, can it? You are using one yourself, right?
Anyway, happy to help squashing this bug. If you have another idea and want to update the firmware, I'm happy to give feedback, uli :-)

Btw. I noticed there's something potentially off with the german keyboard-layout:
Tried to set the layout to german in v0.90-285, afterwards shift+z produces a captial "Y". Can you confirm this?

...and a One, a PC, and a non-OPi board; all work. There is, in fact, little in the way of board design that could affect the HDMI functionality.

Appreciated.

Yes, I can. Please file a bug report for that so I don't forget.

Alrighty, I think I have found the issue. The lib-h3 HDMI driver runs the HDMI controller with "scrambled" registers, but the allwinner-bare-metal code is all written to be run in "unscrambled" mode, so adding the audio config back didn't do anything. I have fixed that now, and I hope that will solve the issue.

Note that because there is no change to the Engine BASIC repository, the build number has not been increased, so please re-download the v0.90-285 image, and don't accidentally use the old one.

You're the man, uli. That was it! Everything seems to work perfectly now.
Though, I have to say you weren't kidding when you mentioned "BEEP 10 should produce an ear-piercing constant high-pitched beep". I tried the command for the 1st time and was almost going deaf. Also, my wife was going apeshit, yelling at me from the other side of the apartment what the f*** I was doing.... 😅
That IS some nasty command...especially with turned up volume!
Thanks anyway for your quick help, I appreciate it .

Also, regarding that bug report for the Y/Z-issue in the german-keyboard-layout. Any preference where you want such things filed,...as new topic here in the forum or as 'issue' at github?

Fingerhoff Everything seems to work perfectly now.

Excellent. Can you do me a favor and run the following commands on your device and tell me what the results are:

?HEX$(PEEKD($1c00024))
POKED $1ef0014, $42494e47
?HEX$(PEEK($1ee0000))
?HEX$(PEEK($1ee0001))
?HEX$(PEEK($1ee0002))
?HEX$(PEEK($1ee0003))

Fingerhoff That IS some nasty command...especially with turned up volume!

FTR, there is a volume parameter; see HELP BEEP. Also, the default volume can be adjusted using CONFIG 7, ....

Please open an issue on Github.

painintheworld I'm 100% certain that particular Opi I was having issues with was just a lemon.

Would you mind trying it again with the new build? There is at least a small chance that whatever Linuxes you have tried might have the same issue. (And run the above commands as well, while you're at it.)

@Fingerhoff Glad you got it going! I'm 100% certain that particular Opi I was having issues with was just a lemon. I ended up soldering a 3.5mm pigtail jack and doing it that way.

Sure I can, here are the results, uli:

?HEX$(PEEKD($1c00024))	-> 100 
POKED $1ef0014, $42494e47	-> OK
?HEX$(PEEK($1ee0000))		-> 13
?HEX$(PEEK($1ee0001))		-> 2A
?HEX$(PEEK($1ee0002))		-> A0
?HEX$(PEEK($1ee0003))		-> C1

As requested, I have opened the issue regarding the key-missmatch in the german keyboard-layout on github,...so you won't forget ;-)

Also, thanks for hinting me to the help file for the BEEP-command. I already figured that out myself after bespoke situation where I almost fell off my chair. Very "helpful" these help-files, I must say.... :-P

I will try the newest build as soon as possible and post results. I need to do the gamepad tests you advised me on, too.

Thank you!

Ahoy,
Using EB NG V90-271 and 90-287 on a Tauon PC-1 I'm having trouble with no sound on some monitor hardware but sound on others. I'm using 4 things:
1)19" Craig 720P TV/monitor-Sound in composite mode, no sound in HDMI
2) 24" LG 1080P TV/monitor-Sound in HDMI mode
3) VLC w/composite capture card output to LG 24"-sound in composite
4) VLC w/HDMI capture card output to LG 24"-no sound in HDMI
I have 5 19" Craig TV/monitors all the same model number. Two are older version, 3 are newer version. I have 3xCompulab Utilite Pro mini computers. They will ONLY work on the 2 older versions. I believe this has to do with the HDML version, whether HTML 1.3, 1.4 or 2.0. I think the older Craig mons & the HDMI cap card must be HDMI V1.3 and will not make sound from EBASIC NG. Only the LG mon is V1.4 or higher so it works.

PS: the HDMI cap card is a MS2109-based cheapo I grabbed for a few dollars and change. On my Ubuntu ASUS Chromebox the lag is terrible bordering on 1-2 secs making my Amazon Firestick TV unwatchable. On my RPi 4B its much faster and usable but sound refuses to work in any capture program (go figure!). Basically it works the same for the Easycap AV card except its watchable on the ASUS box. No sound in Raspbian. Both are fine for programming in EngineBASIC. db

Those generic HDMI capture devices are a gamble, at least that has been my experience. I have an Elgato HD60 that plays nice with what little I've tried on the Orange Pi. I do have a cheapo USB 2 HDMI capture device that I've been tickled with. I just checked my order history to grab a link and it is no longer available (iorder says "LENCENT Audio Video HDMI To USB 2.0 1080p60" and it works fine at 1080p60 with OBS).

I mostly use an 11.6" HDMI/VGA/Composite/BNC 12 volt DC monitor and it works awesome. I've been planning on making a cyberpunk-ish laptop and may use this monitor...maybe get something a little large for my old eyes. Currently it is stuck to a laptop lap desk with velcro and powered(powering the monitor and Pi) by a 12v/5v (6ahr at 12v) lipo battery , and using a most excellent mechanical keyboard that I snagged on Prime Day for $22 or so.

It has been hit or miss on various Vizio and Samsung televisions. I will try to grab parts numbers this weekend, as it may help someone else in the future. Since the wife has a three day weekend, I will also test the gamepads like I told uli a while back I would and get those results out to the community.
