HDMI RX550 sound issues

ginn · November 4, 2018 at 1:32 PM

Hello,

I have sound issues with Kodi:

- Sound randomly sizzles/jump out when playing videos.

- Sound always sizzles with Kodi UI sound.

Changing sound parameters don't help to reduce theses issues.

Enabling or disabling passtrough don't help to reduce theses issues.

Also, passtrough don't work correctly on some video (At least videos with DTS-HD MA):

On start it don't work (No sound).

But, during the video play, if I disable all output format, then disable passtrough and the re-enable it and re-enable formats, it work.

LibreElec: 8.90.006

CPU: Intel G630T

RAM: 4GB

GPU: AMD RX550

Sound system: LG SK10Y (Connected to GPU with HDMI))

Screen: LG OLED65C8 (Connected to LG SK10Y with HDMI ARC)

Full log: DL.FREE.FR

Thanks.

Please use pastebin or the LibreELEC internal Loguploader option to provide debuglogs. Noone downloads files from "somewhere"

Thanks

FYI, I'm having same problem on Radeon RX 550 on LE 8.90.007. Random audio dropouts in passthrough mode on AV receiver connected via HDMI.

CPU is Intel G4500, 8GB of RAM.

AV receiver is Yamaha RX-A850.

TV is Samsung UE55HU7500.

Will try to upload logs.

I have exactly the same problem on both amd cards, R7 260 and R9 270x with libreelec reborn remix build, I uploaded logs here:

I don't have access to these cards at the time so I can't do other tests.

It seems AMD HDMI drivers are buggy

Anything is possible, AMD drivers for Linux did come late to the party.

Try the Milhouse Generic build, that is the latest we can offer for LibreELEC.

It's possible a newer Linux kernel as well as newer Mesa drivers could have fixes for AMD hardware.

Tried latest Millhous build - same thing

If so, report the problems in his Kodi thread, and include a debug-enabled kodi.log file.

Hi There, i did start a new thread but was pointed to this threads...

I recently upgraded the GPU in my HTPC to a AMD RX550 and updated LE to 9.1 however I now have major Audio issues. The HTPC is on a passthrough on my AV Amp (Yamaha RX-A3070) then to my TV (Sony KD55XD9305)

If I try to play a film with the Audio passthrough on the sound is very glitchy and cuts on and off, if I turn audio passthrough off and revert to PCM the audio works but is very distored and noisey, if i have the GUI sounds on then they also echo. It seams to play DTS HD better than Dolby True HD but both are poor

The audio settings on Kodi show i have 6 audios outs, 5X HDMI numbered 0 to 4 and a pulse default bluetooth audio however i only have 1 HDMI on my GPU. the HDMI labeled #3 shows as HDA ATI, SNY SONY TV *02 on HDMI #3 and is the only output i get any sound on (so i have selected it as my GUI & Passthrough audio out).

i have uploaded 3 log files, the Log file adresses are...

http://ix.io/1cfl - DTHD log file

http://ix.io/1cfn - DTS HD log file

http://ix.io/1cfo - PCM log file

Any ideas would be helpful

I am getting ready to replace my low profile GT-1030 with a low profile RX-550 hoping to get HW decode of 10-bit HEVC in my HTPC... I haven't been able to find any updates as to whether these HDMI audio issues with the RX-550 have been resolved. Any ideas or links?

Thanks all!
