HikariKnightOP•1/15/24, 7:11 PM

if it is not then you did not follow the instructions from enable-vfioenable-vfio

HikariKnightOP•1/15/24, 7:12 PM

alternative command without ls-iommu is

lspci -nnk | grep -iP "(nvidia|nouveau|vga|amdgpu|vfio)"

lspci -nnk | grep -iP "(nvidia|nouveau|vga|amdgpu|vfio)"

@Kyle Gospo I have bluetooth audio stutters on the latest testing build.

RodoMa92•1/15/24, 7:26 PM

Did something change pipewire wise?

deck?

KKyle Gospo deck?

RodoMa92•1/15/24, 7:27 PM

Yep

RodoMa92•1/15/24, 7:28 PM

Seems almost like it's dropping packets.

RodoMa92•1/15/24, 7:29 PM

It feels like whole chunks of audio go missing each 15 seconds apart approximately.

RRodoMa92 Yep

This part of steamdeck-dsp is now working (bt config based on hardware)

Kyle Gospo•1/15/24, 7:30 PM

and this patch from valve is no longer applied, it's what was causing popping

Kyle Gospo•1/15/24, 7:30 PM

I'll test and see if I can reproduce later today

KKyle Gospo https://gitlab.com/evlaV/valve-hardware-audio-processing/-/tree/main/wireplumber...

RodoMa92•1/15/24, 7:32 PM

Oh, yeah, that might be it then.

RodoMa92•1/15/24, 7:32 PM

It feels like warping in time forward, so that patch removal might just be the effect I'm hearing.

Kyle Gospo•1/15/24, 7:33 PM

interesting, that patch totally broke non-bt

Kyle Gospo•1/15/24, 7:33 PM

so maybe there's another fix we can do

KKyle Gospo interesting, that patch totally broke non-bt

RodoMa92•1/15/24, 7:33 PM

Lol

RodoMa92•1/15/24, 7:33 PM

LCD btw

RodoMa92•1/15/24, 7:33 PM

Since OLED has different hardware inside.

RodoMa92•1/15/24, 7:35 PM

Might have understood what the problem is.

RodoMa92•1/15/24, 7:35 PM

Disabling gaming mode on the buds seems to have improved it.

RodoMa92•1/15/24, 7:36 PM

It might just be that there is not enough audio buffered sent from the Deck I guess.

RodoMa92•1/15/24, 7:37 PM

(And the bigger quantum was masking it before)

RodoMa92•1/15/24, 7:40 PM

I have slightly higher latency than before, but it's not as useless as with that patch (the delay was quite noticeable)

Sabrina~(Jen)•1/15/24, 7:40 PM

that's weird. it says my driver is amd_gpu....but i turned on virtuilzation

CharlieBros•1/15/24, 7:42 PM

Man, I'm livid, YouTube suddenly started to have issues, first, it usually keeps playing the sound but the video becomes static, then, it just keeps loading and loading until I manually move forwards. I tried clearing cache, use a private window, etc, and it ended up being that it tried to load ads, but because I have ublock origin, the player cant load them, and doesn't know what to do, so it just craps itself

CharlieBros•1/15/24, 7:42 PM

So if any of you are having this issues, yeah, it's the ad blockers

@Noel ^^

RodoMa92•1/15/24, 7:48 PM

Nah, it's just Google and their money.

RodoMa92•1/15/24, 7:48 PM

@CharlieBros

RodoMa92•1/15/24, 7:49 PM

Use FreeTube and you have resolved the problem.

CharlieBros•1/15/24, 7:49 PM

Oh, no, I know about Google being greedy bastards, It's just that the ad blockers are causing the issue

RRodoMa92 Use FreeTube and you have resolved the problem.

CharlieBros•1/15/24, 7:49 PM

I was JUST reading about it, and it has a mac version, hurray!

CCharlieBros I was JUST reading about it, and it has a mac version, hurray!

RodoMa92•1/15/24, 7:49 PM

Yep

RodoMa92•1/15/24, 7:50 PM

Forget about YouTube and use other clients until google kills them all, as sad as it sounds XD

RRodoMa92 I have slightly higher latency than before, but it's not as useless as with that...

RodoMa92•1/15/24, 7:51 PM

Yep, they are gone.

RodoMa92•1/15/24, 7:51 PM

it still needs some tweaking, but I'll probably report this to bluez then, if that's the default.

RodoMa92•1/15/24, 7:52 PM

I'll maybe try on another Bluetooth transmitter first.

SSabrina~(Jen)that's weird. it says my driver is amd_gpu....but i turned on virtuilzation

Sabrina~(Jen)•1/15/24, 7:57 PM

I found the problem

Sabrina~(Jen)•1/15/24, 7:57 PM

I didn't enable iommu

Sabrina~(Jen)•1/15/24, 7:57 PM

Silly me

Sabrina~(Jen)•1/15/24, 8:05 PM

...i enabled iommu

Sabrina~(Jen)•1/15/24, 8:06 PM

Sabrina~(Jen)•1/15/24, 8:06 PM

and amd-v is enabled

Sabrina~(Jen)•1/15/24, 8:06 PM

but it's not working

SSabrina~(Jen)that's weird. it says my driver is amd_gpu....but i turned on virtuilzation

HikariKnightOP•1/15/24, 8:07 PM

turning on virtualization does not touch the gpu
turning on vfio does not touch the gpu
doing what enable-vfioenable-vfio tells you to do at the end after enable-virtualizationenable-virtualization is what actually binds the gpu to the vfio driver

HHikariKnight turning on virtualization does not touch the gpu turning on vfio does not touch ...

Sabrina~(Jen)•1/15/24, 8:08 PM

I only have one gpu-

easiest would be to download and run ls-iommu from the terminal https://github.com/HikariKnight/ls-i
