** Added video link so you can hear what I hear. See link at the bottom **



I may make a video and post a link so you all can here what I mean but any other AmigaOne X5K owners here experience sound issues while running MorphOS?

I am using MorphOS 3.20 and today while trying the new Wayfarer 10 with YouTube and then tried to play some games as well, within maybe a minute or two sound that starts OK becomes a static crackling mess, even tin like sounding.

My X5K has an audio board as they did not come with onboard sound. Under Amiga OS 4.1 all sounds great. I use the same audio port on the card out to a small A/B splitter as I also use old gaming systems on the same TV so nice to get nice sound from them when I want.

Under MorphOS or AmigaOS I have the switch to the right selector and under AmigaOS fine, under MorphOS anything that outputs sound starts OK but within a minute or two turns to poo. haha

When I can I may try bypassing the splitter "just in case" but hard to get behind the X5K on the desk so don't have time today but will later.

Just seems weird under Amiga OS, same port, same speakers, all is perfect. Under MorphOS starts out OK but then degrades.

Anyone else have that issue before?

It would be helpful if you would actually tell us what kind of audio board you use ...

Added video link so you all can hear what I am hearing with bad X5K audio issues.

MorphOS sees the card I am using just the same as AmigaOS does a
CMI8738 Hifi 16 Bit Stereo++

Any help would be great!

As I purchased the X5K back in 2016 I don't remember the brand and model of the card so other than what AmigaOS and MorphOS see as the driver, CMI8738 Hifi 16 Bit Stereo++, that is all I know for now.

It will come to taking apart and getting the card out to see and my guess a generic card of some kind but it has been almost 10 years so I don't remember.

Unless there is some app in AmigaOS or MorphOS that can scan the hardware inside my X5K and show what model board it is?

showconfig in a shell usually lists the card IDs found in the system but it can not find the actual model of the card usually.
Either way, CMI8738 is good enough for a start. The distorted audio in the video sounds like the playback buffering gets out of sync at some point and new audio data is filled into the currently played buffer, so it pretty much seems to be a AHI driver bug that only seems to show in MorphOS.

As I only used MorphOS 3.19 a short time and not much audio, what I don't remember is this audio hiccup I now have in 3.20.

I did not run older MorphOS on my X5K so can't see how updates affected this or not in my limited time using MorphOS on my X5k.

Always a chance 3.20 introduced something new?

Are you sure you are running the beta version of 3.20 btw ? :)

Anyway, I did the CMI8738 AHI driver around 2017 when the X5000 started to show up and it didn't change much since then...

You could try to edit the env variable envarc:cmi8738.audio, put the string

Code:

into it, reboot and check if it makes any difference.
