SimpleScreenRecorder has no audio (Solved)

Been trying to capture Youtube video with SimpleScreenRecorder, but get no audio. Anyone done this successfully?
These are audio devices shown by SimpleScreenRecorder, none work.

I have done this with Bionicpup64 with little or no tweaking to ALSA. Not tried with Fossapup as I have pulseaudio installed so I can run other apps.

Why not use yt-dl and download the whole youtube ?

@Geek3579

I can record audio if I install pulse, but thought maybe someone might have found a way to do it on stock Fossapup64. Have never tried yt-dl, may give it a try. SimpleScreenRecorder is a better solution for me since I record from multiple sources.

Thanks for response

Don't have the technical ability to solve the problem with SimpleScreenRecorder.

To download videos with sound --other than from Youtube-- I use addons/extensions. On Chromium & Clones I install Video Downloader Plus; on firefox Videodownload helper [and install the net.downloadhelper.coapp-1.6.3_amd64.deb]. I install classic Add-ons Archive into Palemoon and older versions of Seamonkey, after which I can install NetVideoHunder version 1.20.. Waterfox-Classic can use that and/or Videodownloadhelper 7.6.6. Even though I have classic addon archives installed I think Videodownloadhelper 7.6.6 was a direct addon install.

y2mate.com - can download the full video or just the audio. You may see unwanted ads. This is a better option than recording because the original video sound track is just seperated from the video so the quality stays the same, it is not re-encoded as with recording.

I was also facing the same problem. Someone in the forum suggested me to install pulseaudio.
Now it works perfectly. Also the new version of simple screen recorder to get support of pulseaudio

@wizard :-

I tend to agree with Nic on this one, mate. These YT downloader sites always download the video in question in way better video/audio quality than any screen recorder can achieve.......because the original media streams are being used. TBH, I discovered this problem with YT audio a long time ago, and it's for the same reason that Nic gives; despite that the on-site media player combines everything together so you aren't aware of anything being different, the video & audio streams are in fact coming in separately.....and that's why screen recorders don't pick up on the audio portion. The two are only combined in the on-site player at the "moment of consumption", y'know?

Big Brother did this specifically to stop folks like you and me trying to "unofficially" download stuff. They'd far rather you kept visiting the site; more visits = more 'hits' for them, and keeps their SEO page rankings as high as possible.

It's ALL about SEO these days, believe me..! Google (YT's owners) should know about such stuff; it figures in a large proportion of their bread'n'butter income, after all.

Remember that all videos uploaded to youtube are re-encoded for use on the site by youtube even before we have access to it. The uploader may (very likely) also have re-encoded the video file whilst compiling it, so in most cases you are already sitting with material which has been processed at least twice once available on youtube. Recording it will process it again. Every time the file is processed (re-encoded) there's degration of quality.

I have the same problem using FOSSA. The way I understand things, loopback should help to capture the system audio but It has never worked for me, I feel like there is something else that needs to be done perhaps some alsa configuration file?

[amethyst]

Just checked the y2mate.com option again. It does look as if the audio may be re-encoded again. This is not what we want. So try https://getvideo.at/en/
IMPORTANT - Right Click the highest M4A option and select Save Link As (may differ depending on the browser you are using). This will ensure that you download the original audio part of the video file. The download was very slow with the video I tried (it seems as if it's downloading at the same rate/time the file plays at because it fetches directly from the google stream) but at least it's the original audio track.

I tried Simple screen recorder with Fossa64 and could not get audio to work, also. As I needed a quick solution, I moved on. This is with pulseaudio installed, as I recall. In the end I wrote my own script, and after that i found two other methods (but needing pulseaudio, still).

I suspect you'll find it boils down to one thing. Maarten Baert, the guy behind SimpleScreenRecorder, has taken the path of least resistance. All mainstream distros now use PulseAudio, along with systemd. So he's taken the obvious route, and coded for exactly that combination. It makes his life easier. You can't exactly blame the guy; nobody in their right mind voluntarily MAKES more work for themselves, do they??

We're the "outcasts", "misfits", call it what you like, for NOT "toeing the line", and "following the herd".....y'know? In the eyes of the rest of the Linux community, we generate our own problems....

But who wants to follow the herd ?? What problems new versions of Puppy Linux throw up are more than offset by the help on the PL Forum. I dont know of any linux forum which has such a diverse suite of how-to topics, development and tweaks. Ok, users may have to do self-maintenance, but if you like a challenge, there's plenty of opportunity.

Absolutely, mate..! Couldn't have put it better myself.....

IMO, if Puppy Linux is not going to adopt pipewire or pulse audio anytime soon It needs to start finding solutions to common tasks such as the one presented here.

I am a long time puppy user and a regular use case user, web surfing, simple video editing, netflix, email, video conferencing. It took me years to stumble upon this ALSA configuration file because I had no idea what to search for. ALSA is not user friendly, and to make things worse its documentation is terrible.

The alsawizard, Sound Card Wizard 2 did not generate a successful asound.conf file for this use case.

I don't think it is a FOSSA issue, I had the same problem with previous Puppy Linux versions.

The file attached is a fake mp4, rename it, you will watch a video generated using simplescreenrecorder, and hear claps into the mic, deadbeef playing music, and youtube playing music.

F96_4-radky6-CE (Fossapup64-9.6) uses pulseaudio as do the latest Puppy's coming out of woof-CE.

... adopt pipewire ...

This has been underway for a year/so. It is built into @dimkr's Wayland ISO here, IIRC

I would expect to see it available in most every upcoming forum distro before year's end.

[boof]

fossapup64-9.
/etc/asound.conf not exist, but /etc/asound.state does. are they same purpose/contents-wise? change without improvement is a waste of public brainpower. if it's not different, AND improved, don't bother.

[boof]

OK it works after i appended asound.state with the appendment. now, pls, how do i time automate the on/off to record my fav tv while i sleep, so i can watch it next day, and automate .mkv files to the vlc?

[boof]

set default media player to vlc. that was easy enuf. timing is another thing. not sure if i can set record and stop hotkeys in the serup. i prob can. that would help.

That's as may be; I certainly wouldn't argue with you over this point.

When it boils down to it, however, Pipewire is just another 'user-friendly' GUI for controlling ALSA.....in this case, IIRC, it specifically handles 'routing' of signals between all the other audio applications/layers on your system. ALSA will always be there, because it's so tightly integrated into the Linux psyche you'd have a major job on your hands to replace it. But it's always been awkward to control directly.....hence the likes of PulseAudio & Pipewire, which run on top of ALSA & make the user-experience a lot more 'friendly'.

I'm ALL for 'friendly'.....so long as it doesn't mess everything else up in the process!

Excellent! I'm just about to install it there myself. Ta for the 'heads-up'...

[mikewalsh]

Well, that's weird.

0.4.4 is running very nicely in both Xenial64 and Tahr64 on the D630.....but for some strange reason, after installing it in Fossapup64 9.5 all I get is "symbol look-up error". And this exact same package is running fine in the exact same install of Fossa on the big HP desktop rig....yet here, it doesn't want to know.

How odd is that, huh?
