@bk said in Sound not working with HifiBerry:

Concerning the alsamixer, I assume I have to type "alsamixer sndrpihifiberry" or "alsamixer snd_rpi_hifiberry_dac"? If so, both give me "cannot open mixer: No such file or directory".

No, you should just type alsamixer and note the mixer's name (4th row on the top left menu). For instance, in the screenshot below the mixer is named Headphone.

However, based on the error you're receiving (cannot open mixer) it looks like the device has no hardware volume control (mixer). You may be able to add a software volume control, following the instructions from this page.

@ultra-magnuss I haven't looked at this in a few days. For now I have remapped my buttons to not use the start and coin up button. I leave a putty session open to turn the volume down if someone hits it but I would like to figure out how to fix it. It's not as urgent for now since I have a kind of workaround but I would like to figure this out. I'm sure it's a configuration somewhere but don't know where.

@folly said in Has anyone managed to get sound from the TRS-80?:

@jimmyfromthebay

I found this info on a blog :

Many games did not include sound effects, as audio output was not an intentional feature of the TRS-80's design, but many games used a trick to produce sound effects.

The trick was :
Back in the day, we had to hook a little speaker up to the cassette out line to pick up the audio

So that could be the reason why you don't have sound.

No, these are definitely games with programmed sound and speech, because I've seen YouTube videos of them (and MESS does refer to the machine's sound hardware, as seen in the above pics). It's very strange that the maximum sound output level in MESS is set to 0dB.

I've no idea what the technical machine differences are. There were a whole bunch of systems around at the same time that appear to use extremely similar hardware/OSes, and run identical-looking ports of the same games (I think the Genie is another) but I don't think they're compatible.

I'll investigate adding memory. It was a massive faff to get games working across all three formats, and lots of stuff that seemed like it SHOULD work didn't work because the files were in some sort of different formats despite having the same file extension. If I can get sound working I'll do a little tutorial.

(Planning one for the Dragon 32/CoCo2 as well, but so many things to do and so little time. Currently having an absolutely brutal fistfight with a couple of incomprehensible ZX Spectrum Next emulators.)

@jiryn we only get email notifications for your first version of the first version of your post, FYI.

When I tell Retroarch to reset defaults, I lose all controller access.

yeah don’t do this. retroarch defaults are not retropie defaults and will not work.

@barbudreadmon @Darksavior
So, tested it on all my house hold TVs.

All 4 are Vizio.
My entertainment center TV has issues with the sound cutting out constantly.
The others (Roommate bedroom, my bedroom, and the living room) do not have the same issue.
(I even changed cords, and plugged the system directly into the TV instead of the splitter box)

So I wonder if the TV itself is defective, or is it just incompatible, or what...

I also tested all the ports on my entertainment center TV, same sound issue with each HDMI port.

When I bought the TV in Sep '18, in Oct '18 they had to do a recall on the main board, sending a person out to replace it. Then as of last year, the sound was cutting out again on other channels but eventually stopped, but Vizio sent me a replacement board just incase.. something I didn't/don't know how to install... so it's probably just either the first replacement died as well, or wasn't installed correctly, or the TV is just crap.

@mitu Awesome, this fixes it! Thanks for the help.

@scrumpydaniel

try power up the speaker via usb within the pi4 or by some audio converter from hdmi to 3,5 jack audio and have the audio setting of pi4 to hdmi and not 3.5 jack.

@john_carter No, it's is when I enable the VMS video driver and then the audio fails to work under HDMI. I haven't seen any other reports of this.

It's a common issue, since the HDMI audio is handled by the KMS driver automatically. It's been widely reported - in fact when the KMS driver for Pi4 was announced, it was one of the changes included (see this forum post). Here in the foruns - see this topic.

And that did it.

After my last reply, I removed the gamepad physically, and put the alan-1 flight yoke adapter in position one of the RPI.

Then, I deleted the Mame-2003-plus config files at \home\pi\RetroPie\roms\arcade\mame2003-plus\cfg

I went into Retroarch config from Retropie and went to bind inputs for port 1. I changed it from Gamepad to Gamepad with Analog, set it to left analog, then mapped only the analog and four buttons.

Next, started up Star Wars, and mapped input for this game to the Analog X/Y and buttons.

Deadzone gone!

Settings and everything held after reboot.

Thanks for all the help!

@buffyp00h said in Audio stutter in some SNES games on surround receiver:

All have the same problem on soundbar systems (and likely also on surround receivers).

I just don't get why these particular games generate hdmi sound that gets wrecked by so many setups, one would think there was a way to fix this at the source - the generation of sound on the pi/other device.

Just my 0.02 here, the world of modern TVs and home theater/surround sound devices is needlessly complicated for these simple old tasks we are trying to recreate here with simple digital signals (ironically that are emulations of old analog signals).

What I would try to see if it helps:
Many TVs have a "game mode" that is intended to reduce or eliminate "signal processing" to enable a more pure, delay free signal and timings. Many surround sound receivers have something similar, although it is usually called Pure Audio or Direct Sound mode. You might see if your receiver has this option and try it to see if it eliminates audio hitches.

For what it's worth, I have an Onkyo receiver at home and even with modern consoles I have noticed that something in the HDMI convergence where all video inputs are routed to a single HDMI output to the TV will cause a 'gap' in sounds sometimes. (After a dead silence of any kind, the first sound made is either dropped entirely or gets cut so I only hear part of it before normal audio resumes. Sort of like the audio stream has to buffer up before it becomes stable again.)

EDIT: Hit the submit button too soon and wasn't done typing.

@mitu said in Making sound back after december update broke Pixel Desktop:

sudo apt remove lxplug-volumepulse

Yes! Many thanks @mitu, my menu bar is back. You're fantastic!

@mitu ok, i will do just that. i will have my old image restored, update the OS and retropie, then follow the instructions in the previous thread.

@danmac2 said in No Dialogue or Music in PSX ROMS (pcsx-rearmed):

@dankcushions I have every BIOS you can think of in the bios folder

ok, and the verbose log?

@MeltedPineapple hello! I suspect you're having an eXoDOS version of the game. @mitu is correct in saying there are parameters to help you configure your setup. To have the dosbox.conf (or any conf file or commands) you did use to launch the game would help a lot! Off top of my head here are some parameters you can use to run the game:

c:\> monkey.exe r <- enable Roland MT-32 (requires specific files and setup) c:\> monkey.exe i <- enable internal speaker c:\> monkey.exe a <- enable Soundblaster and Adlib (most compatible) c:\> monkey.exe v <- force VGA

You can use a combination as well:

c:\> monkey.exe a v <- enable Soundblaster and VGA

Search for Monkey Island reference card for DOS on the Web to get more keyboard shortcuts and interesting info. The most interesting shortcut for you would be Ctrl + S which turns on / off the sound (only working for Internal Speaker though).

Note: my recommendation would be for you to give a try to ScummVM for anything Lucasfilm games/LucasArts related. Very easy to use and you'll get the best experience possible. Check Retropie docs here for installation and ScummVM wiki to properly configure the games.

@mitu you are totally right. I switched to carbon and everything sounds great. Thanks for the help.

@yfzdude Totally worked. Thanks for pointing out the doc.
