[Bug 86351] HDMI audio garbled output on Radeon R9 280X
https://bugzilla.kernel.org/show_bug.cgi?id=86351 --- Comment #35 from Christian Birchinger (jo...@netswarm.net) --- After a success report in the previous comment i've installed a 5.0.3 kernel on my system. The audio seems good so far. I'm trying to keep the load low in the background to make sure this time it's not just fine because there's also a video playing. It's been playing for 10 minutes without dropouts so far, i'm cautiously optimistic at this point (again). If you have this problem and the possibility to test with a 5.0 kernel (or maybe 4.20 from the previous comment) give it a try please. -- You are receiving this mail because: You are watching the assignee of the bug. ___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

https://bugzilla.kernel.org/show_bug.cgi?id=86351 --- Comment #32 from letha...@gmail.com --- It's still not ok for me with rx550 on a core2duo. The HBR audio now starts playing to the audio receiver thanks to the fix. But the sound is "flickering", it improves a lot by maximizing the audio buffer, and even more by putting load on the cpu(vm), but it's still not usable. Couldn't reproduce this issue on a rx550+4770k. So it could be linked to older motherboards/cpus slower scheduling or something? Iirc, i also tried an rxvega on the core2duo, couldn't reproduce it either. I still have tests to do: retry it with another linux distro on the old computer. I really don't understand what or why anymore. -- You are receiving this mail because: You are watching the assignee of the bug. ___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

I've tested stereo and DTS passthru using mpv and sound is fine without any distortion regardless of system load. Maybe a few others who still suffer from this issue want verify it too, but i think the bug seems fixed. -- You are receiving this mail because: You are watching the assignee of the bug. ___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

https://bugzilla.kernel.org/show_bug.cgi?id=86351 --- Comment #28 from Andy Furniss (adf.li...@gmail.com) --- Yea, I fount that you need io load, I use mprime - but not the test that just stresses cpu... Of course using pulse, as most people do, avoids the bug as it uses sound different from alsa. TODO - try and get jack to recreate what pulse does.

To be concrete: stress -m 1 is enough to let the sound play normal, stress -c X results in load, but does not change the audio.

I've tried some of the tips discussed in the Arch Linux forums (https://bbs.archlinux.org/viewtopic.php?id=181764), but I've not been able to get it to work. If I remember correctly, the driver bundled with the Radeon Catalyst-driver fixed the issue. Due to the recent kernel I'm running, the driver will not install.

https://bugzilla.kernel.org/show_bug.cgi?id=86351 --- Comment #23 from Andy Furniss --- I don't have a 270X anymore which I was using when first commenting in this bug. My current R9285 Tonga also has this issue and I've just tried setting 2048 (runtime) for prealloc and it doesn't help me. I do think this is a sound driver issue though as pulse audio works, though it was a different test = with fglrx the issue is also present when using alsa but not pulse. The difference seems to be that alsa direct uses SND_PCM_ACCESS_RW_INTERLEAVED and via pulse it uses SND_PCM_ACCESS_MMAP_INTERLEAVED -- You are receiving this mail because: You are watching the assignee of the bug.

Anyway, a value of 2048 seems to fix the issue. I've tried normal stereo, DTS and DolbyD and the sound was fine and without dropouts.

https://bugzilla.kernel.org/show_bug.cgi?id=86351 --- Comment #20 from Christian Birchinger --- The kernel documentation for CONFIG_SND_HDA_PREALLOC_SIZE has this: Note that the pre-allocation size can be change dynamically via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too. I don't have any "pcm" sub directories in /proc/asound/cardX.

No, I've tried many things as recorded in the FDO bug I linked. It's certainly a strange one, but the only way to get working sound I've found is to have enough CPU load across all my CPUs (just maxing one won't do). By luck for me my only real use case is HDTV and decoding in s/w is enough load. When there is no load it's like just one chunk of buffer gets repeated and this may initially contain old sound from a previous loaded run. Doing not much will advance the buffer. With more, but not enough, load the sound is almost OK, but there is a bit of crackle. This does seem to need purely CPU load, as I said in the other bug I can reproduce from fbcon without X and temporarily "fix" the sound my compiling something with make -j5. My CPU is AMD Phenom II x4 965be, but IIRC others have seen this with intel. Whether working or not interrupt counters rise at the same rate. Previous card = HD4890 didn't have the issue in the same box with the same TV with almost the same s/w. -- You are receiving this mail because: You are watching the assignee of the bug.

As soon as the desktop is "idle" the sound becomes garbled again. Playing a video also has working sound. However only stereo seems to work. There's not enough for passthru Dolby D.
