While PA in the beginning certainly wasn't manna from heaven, it still was a godsend; pulseaudio exposed all the inconsistencies, flaws and straight out bugs in the alsa driver implementations.
The reason so many people had issues with PA was not PA but the brokenness of the underlying system that PA exposed for the first time when trying to use all these drivers in a systematic way and build functionality on top of it. It took years of fixing all the drivers and PA - unfortunately - got a lot of undeserved flak.
PA is the reason that Linux has a halfway decent audio subsystem, being able to deal with all the modern devices; thank you, PA devs.
I find it hilarious that people are festive about PA being replaced by Pipewire - if PA hadn't paved the way, the Linux driver landscape would not be in such a good shape today and Pipewire would 'fail' in exactly the same way that PA 'failed.
I'm grateful we got a reasonable system out of PA eventually but damn it took time and I agree it is today better than what we had with ALSA. But as I remember it audio sucked with ALSA until it didn't and then we had about two good years of audio before PA came about. Then we had 8~ years of crap again and yes a lot of it was definitely due to really bad drivers and masked inconsistencies in the past.
That's not my point tho, my point is that PA didn't sweep in and save us, in fact it at first pushed us back A LOT. And claiming otherwise is a disservice to ourselves when we consider additional radical change. Such as Pipewire and and Wayland.
That argument I don't quite follow. Would you consider rephrasing it? My question is; how did PA set back Linux sound if it did expose all those flaws in the audio driver in the first place?
Not everyone is a power user. At this time I was in university and Linux went from a reasonable choice to an unreasonable due to sound not working again.
If you care about real world usage, PA set us back years when Ubuntu made it default.
> Linux went from a reasonable choice to an unreasonable due to sound not working again.
But that's the crux, isn't it? Linux sound was not not-working because of PA. Linux sound was not working because it was fundamentally broken with drivers that had wildly different behaviors. Everyone was hacking around broken drivers all the time, I distinctly remember how I had to recompile the kernel back then to get some custom-fixes for my setup in because the driver was so kaput.
Only with the introduction of PA was there finally a way to test and evaluate the drivers in a systematic fashion.
So, in short, my point is this; any software that - in this broken state of Linux audio - tried to introduce a software that made available the features the drivers proclaimed would have run into exactly the same problem as PA. Because PA didn't introduce the problem, PA made it visible.
It's like blaming the doctor for diagnosing the illness.
So, while your experience was that sound suddenly wasn't working anymore because Ubuntu configured the default setup to use PA, for lots of people that sound never worked this was fine - because their drivers weren't broken.
Alsa is fine, if you needed absolutely no features whatsoever. This weird glamorization of alsa as sufficient or at all adequate feels like itcs true, for only rhe most basic basic basic of users.
Anyone who has ever plugged in a usb headset or connected a bluetooth headset or plugged an hdmi output into their laptop knows the value of pulseaudio. It's role as a modular, pluggable, controllable audio intermediary layer is invaluable: it has a great control panel that lets you say, ok app, start sending your output somewhere else now. Even if you only have one soundcard ever: it let you adjust per app volume! Utterly basic need. To propose that users ought have been fine without these basic capabilities is insanity. Alsa was insanity.
Alsa was a dead, impotent, lifeless husk. It let apps output audio to a device, if you knew to try various hardcoded strings like hw:1.0, hw:2.0, hw:2.1. But that was all alsa was good for. One couldnt open a control panel & change the volume of an app. One couldnt send an app to a new output (bluetooth, hdmi, usb audio). Trying to get a sound card to pick between various output modes, for optical output for example, was hell: i spent literally days getting optical audio going. Everything required careful scripting in a shitty awful .alsarc dsl to do anything good.
Pulseaudio made it all much easier.
I have no clue why anyone would valorize alsa. It was incredible finnicky, super hard to configure. It feels like certain sects just want to spread poison against linux & freedesktop. There have always been reactive, outraged camps. Eternally dismayed at progress, at better. I just can't take seriously the thought that alsa was an appropriate & adequate tool for end users, in any way though. It's ridiculous: nothing worked without careful careful delicate scripting & trial by error, and the system was utterly static, unable to respond to change. Alsa was not an end user system, unlike pulseaudio: it was an api for software. Pulseaudio changed the game. I am so tired lf hearing pretenses that alsa was ok or enough. It never was amything remotely adequate. The nonsense hate has to die. Progress was required. I saw it work flawlessly on many systems even in the earliest days. It wasn't & still usually isn't required. I don't see what anyone could be asking for. It just seems like a need to sow doubt.
Alsa just worked but had limitations. Some apps grabbed sound and you could not play sounds from other apps. Often, one app could play sound at a time. It depended on whether your sound card could handle several streams IIRC. Each major desktop environment had its own sound server to work around these limitations (KDE's aRts, Gnome's ESD).
PulseAudio let us have a common stack instead. There were bugs (PulseAudio was probably a bit buggy at first, and also hit audio driver bugs because of the new ways of using them). The transition was rough and PulseAudio is not perfect too but is it there for reasons and solves many issues.
Now it is being replaced by PipeWire, probably for the best (more efficient, can replace JACK too, making sound management much easier on Linux), but PipeWire leverages experience from PulseAudio.
I lived the transition to PulseAudio and it went well for me and probably a lot (the majority?) of people. Some things could probably have been handled better, especially the (too early?) transition. I think PulseAudio still is/was a good thing.
Consider me in the same camp. When I set up audio on my linux pc back in the day, the only thing I had to do was enable the alsa daemon to restore volume levels at boot and everything just worked. Then later Pulsaudio was kinda forced on me and I didn't (and still don't) understand why it was needed, it was something about allow multiple applications outputting audio at the same time but that worked just fine with alsa? Plus it didn't work well: under load audio would stutter which was extremely annoying as I listened to music quite frequently while working on my computer, a problem I did not have with alsa. So there I was with a shiny AMD Athlon 64 3500+ that couldn't even play mp3's straight.
