Audio heavily distorted on a Hades Canyon NUC8i7HVK #449

Open castrojo opened 5 years ago

castrojo commented 5 years ago

Describe the bug:

Audio out via HDMI or Displayport on a NUC8i7HVK results in garbled audio

To Reproduce Steps to reproduce the behavior:

  1. Install Clear on the NUC with the desktop-autostart bundle
  2. Select audio out in the gnome sound capplet to either hdmi or displayport.
  3. Audio crackles to the point of being unusable on browser and other sound-using apps

Expected behavior

I found other people with this problem in other distros with this hardware, and the solution appears to be to set tsched=0 in pulseaudio's default.pa: https://fedoraproject.org/wiki/How_to_debug_PulseAudio_problems#Playback_problems.2C_crackling_or_skipping

When I installed Ubuntu 18.10 it had the same problem, and the above solution resulted in working audio. However using that same setting in Clear results in no audio at all. Plugging in headphones results in perfectly working audio, it's just when HDMI or Displayport is selected that there's a problem (I've tested with both a DP monitor and a TV's HDMI port).

I also tried this solution but it made no difference: https://forums.intel.com/s/question/0D50P0000490UT5SAM/how-to-fix-audio-pops-in-linux?language=en_US

ahkok commented 5 years ago

confirmed. My system has the same, unusable HDMI out audio issues. gameplay and multimedia are severely affected and I have to resort to headphones as well.

abecastillo commented 5 years ago

@miguelinux can you take a look at this issue?

ghost commented 5 years ago

Hi

I think i have the solution for you. I am using gentoo linux and I had the same issue. I've changed one option in the Kernel and the audio works perfectly for me.

Here the Kernel option.

CONFIG_HZ_PERIODIC

set it to: Periodic timer ticks (constant rate, no dynticks)

I hope that resolve your problem too.

tpleavitt commented 5 years ago

@chivakker , can you look into this issue? We have a hades canyon for you to test with

chivakker commented 5 years ago

@tpleavitt sure, let me know how I can get the hades canyon.

ahkok commented 5 years ago

The following workaround actually worked for me:

Add to: /etc/pulse/default.pa

load-module module-udev-detect tsched=0
ahkok commented 5 years ago

Well, let's make that last statement a bit more correct:

The cracking is significantly less. But it's still audibly there and prominent. However, I can live with it because I grew up in a time when vinyl records skipped and audio tapes ate themselves.

brockwood commented 5 years ago

Greetings. Any progress made on this? I had hoped to give Clear a try on my Hades Canyon NUC but this is preventing me from long term use of the distro.

buckyboy0 commented 5 years ago

I have been experiencing the same problems. I have found that it is working on Ubuntu 18.10 however. On everything else I have tried it sounds high pitched like the game Worms and distorted. I have confirmed its not working on Ubuntu 19.04, Kubuntu 19.04, manjaro-kde 18.1 also tried daily build of Ubuntu 19.10. At least with one working distro this may help track down the change that killed the HDMI audio. There seems to be another issue where the audio does not kick in for a couple of seconds which still effects Ubuntu 18.10. When running the sound continuously it seems to be fine.

Got the same problem at my hades canyon box. I hope it is fixed soon.

cybik commented 4 years ago

Using @ahkok's solution, the crackling gets minimised. There's some, er, other oddities arising, but I can report that audio is at least usable after using the fix.

nathanske42 commented 4 years ago

The following workaround actually worked for me:

Add to: /etc/pulse/default.pa

load-module module-udev-detect tsched=0

Adding tsched=0 to load-module module-udev-detect in /etc/pulse/default.pa, then modifying the following settings in /etc/pulse/daemon.conf fixed the crackling problem for me.

default-sample-format = s24le

resample-method = speex-float-5

stevenidavis commented 4 years ago

tsch

Two other steps I found which helped Second:

Edit /etc/modprobe.d/alsa-base.conf.
Add to the end of the file: "options snd-hda-intel vid=8086 pid=8ca0 snoop=0"

Third:

Edit /etc/pulse/daemon.conf
Find and replace:
"default-sample-rate = .*" -> 48000
"alternate-sample-rate = .*" -> 96000
"avoid-resampling = .*" -> true
"resample-method = .*" -> src-sinc-best-quality

cybik commented 4 years ago

Unfortunately, even with arachnoid's recommendations (and editing others' recs into the default.pa file), a Pop_OS install with everything at latest still has accelerated video/audio playback, and games that have "specific" audio buffer code appear to essentially underrun the audio buffers.

What's wrong with Hades Canyon's audio?

stevenidavis commented 4 years ago

Despite arachnoid's excellent advice, src-sinc-best-quality is deprecated. Try one of the speex resamplers.

I also found disabling the intel integrated graphics made my system significantly more stable. Pop! might have the hybrid graphics solution better worked out

Thanks everyone for the important comments.

With Ubuntu 21.10, kernel 5.13.0-28, I still had the audio "cracks" on both HDMI and DP outputs.

I have followed all indications above and it seems to have been fixed.

I have added to /etc/pulse/default.pa load-module module-udev-detect tsched=0

While I have changed in /etc/pulse/daemon.conf

default-sample-format = s24le
resample-method = speex-float-5
default-sample-rate = 48000
alternate-sample-rate = 96000
avoid-resampling = true

Then in /etc/modprobe.d/alsa-base.conf I have added. options snd-hda-intel vid=8086 pid=8ca0 snoop=0

It seems to work.

Thanks everyone again.

Ordered a Hades Canyon BNIB and it will arrive shortly. Does anyone here have any opposition regarding the overall Clear Linux experience, aside from this glitch?

Any recommendations towards any other specific debian-based distribution with minimal issues encountered?

Will be contributing when/if issues arise.

Great PC, 100% Linux compatible.

The audio glitch has been fixed like I wrote in my upper post.

The only problem I still have is related to reboot: if I reboot Win10, the system restarts with no problem; if I reboot Linux, the system hangs at the BIOS logo and I have to switch it off and on again.

Where do you plan to buy? Found a good price? (my son is interested)

Found a one-off BNIB with ssd and ram bundled (still sealed box) for 750 USD :) - ebay
