Hello!

Not sure the issue is with upstream or with guix system.

While streaming/watching movie on some (more than one) websites, audio
has constant cracking sounds and voice of characters in the video
becomes robotic.

When I stream/watch the same movie on ungoogled-chromium, the audio is
just fine.

This issue with Icecat has been there for quite some time (across
multiple updates). I also tried running IceCat on safe-mode and got the
same issue.

INFO: My Guix System and Icecat are up-to-date.

Regards,
RG.

If by ‘robotic’ you mean (extremely) low-pitched then, yes, this
has been the case for roughly the past half year.

I asked around on IRC, even sending URLs to innocent people who
were unable to reproduce the problem, so I then assumed it wasn't
in Guix proper. I almost never watch videos on the Web so I
didn't care much, but you might be happy to learn you're not
alone.

Could you share a (free) example URL?

Kind regards,

T G-R

I believe the cause is "media sources", although I'm not sure
exactly what that is, if you disable it it seems to "fix" the issue.
I found this solution from some old firefox bug reports that seemed to describe
similar audio distortions.

A good site to test it on is nicovideo.jp, since on other sites if I
disable mediasources the videos just refuse to play altogether.
So for example here is a reference video, I simply clicked the first
video I saw and it reproduces the audio distortion:

When I play it the audio is very low pitch and crackly. However, if
I open about:config (just enter about:config into the address bar),
search for "mediasource", and then double click
"media.mediasource.enabled" so it shows false, then reload the video
and it plays perfectly without any distortion.

As I mentioned though, most sites seem to not like it when
mediasource is disabled, so it's not a perfect solution, but at
least it shows where the problem lies.

Ison,

Thanks so much for your answer!

Indeed: my sole use case for Web video seems to insist on whatever
this feature is. I can't link to it here for freedom & legal
reasons, but let's say their content is *majorly* ball-based.

With .mediasource disabled, I get an error:

“Your browser does not support the playback of this video.
Please try using a different browser.”

I'd really rather not.

I remember getting this same error in Epiphany when I tried to
play it there. At least now I have a lead…

Thanks again,

T G-R

I'm not sure, but this could be related to playing media files with DRM.

If I recall correctly, last year, when I visited any news post on https://www3.nhk.or.jp/news/easy/on Debian 9 using Firefox ESR, the browser would ask me to enable DRM. If I answered NO, then I would see the

“Your browser does not support the playback of this video.
Please try using a different browser.”

message (or a similar message) instead of videos, and the audio player would display blank (the player that should show up when clicking the big dark blue button that says ニュースを聞く). If I enabled DRM, the media would play fine.

Visiting the same website now that I use IceCat on the Guix system I get the distorted sound in videos and no audio player.

I wonder if people using IceCat in other distributions have the same problem. I was going to report this issue to Gnuzilla, but it seems their mailing list is not very active.

I also have this problem with icecat. With ungoogled-chromuim the video
is scrambled. I wonder if the two issues are possible related.
