Why I Dislike PulseAudio
Pulse audio is un-friendly toward all Unix-like platforms (including and especially Linux). I have had every problem in the book with Pulse audio on Linux. I haven’t the disrespect to defile my NetBSD system with it(perish the thought!). I personally consider it hostile software and counterproductive to even engage with it. It’s not limited to taking up 90+ % of the CPU. It also:
- Has buffering issues which cause sound to stutter, jitter, and basically sound like crap. Today. Now. On at least two Linux systems I’m forced to use (forced if I want to play these modest games under Linux). One is Ubuntu and the other is Fedora and they are patched to the hilt. It often takes more CPU than the games I play under Linux do!
- Doesn’t actually support some of the sampling rates it advertises to clients. Ie.. insufficient checking on it’s operational parameters. Then it won’t re-sample, or if it does, does so in non-realtime (ie.. poorly).
- Almost never works with the hardware mixer on the systems I use. Ie.. changing volume either creates noise, doesn’t work, or mutes the whole channel and makes it UN-adjustable.
- Skips and jitters in bully-victim scenarios with other system daemons as they try to do (often very little) tasks on the system.
- Mis-identifies mixer controls (ie.. headphone port is wrong or missing, line out is mismatched etc..)
- Bugs out or overreacts to sound events like removing a headphone from the headphone jack.
- SIGSEGV then takes some client apps with it (Chrome, Skype, etc..).
- Often skips or jitters the audio while adjusting volume.
- Breaks or jitters input streams when adjusting line-in or mic volume.
- Often has a freak out when one client plays at one rate then another client uses a faster rate. The first (slower) client then goes at the higher rate and you get Alvin and the Chipmunks.
- Tends to “ruin” other configurations. Ie.. it creates dependencies in Ubuntu that (especially recently) make it impossible to uninstall and replace with alternatives without custom compiling packages (firefox depends on it). Another example, you can’t get esound anymore since they force a (inferior and fake) replacement pulseaudio-esound compatibility crapware (that’s shares all of Pulseaudio’s issues plus adds a few of it’s own). You’ll have big problems just going back to ALSA or OSS. Especially with their version of mplayer (where they’ve married it to pulseaudio too closely). I love mplayer. How dare they sully it with this.
Pulseaudio is way too over-complicated. It’s some dream of Lennarts while he was at a rave or something. Maybe he fancies himself some kind of sound engineer. *YAWN* *SHRUG*. Here’s me … wholly unimpressed despite the clubware he sports at conferences. News flash, Lenny, while you are a brogrammer you aren’t a member of The Crystal Method, “G”. Hmmkay?
Every single other solution in the same or similar space is MUCH better. I’m thinking Jack, Arts, Esound, etc.. They may not have all the features, but they WORK, generally. I’ve had Pulseaudio on at least 7 machines. It worked acceptably on ONE. Hand waving about “it’s better now” was old 3 years ago. It’s not better, just more bloated. I have (way) more complaints and buggy, anger inducing experiences with Pulseaudio, but I guess I’ll end here. I consider it one of the biggest PoS parts of Linux overall. It’s like the Kyoto Climate accords. It sucks the air out of the room and provides a very sub-par “solution” (that isn’t) that occupies the space where something much better should be. I doubt anyone is still reading this, so I’ll leave my further issues as an exercise for those who still choose to drink the Lennartix^H^H^H Uhh, I mean Linux kool-aid. I’m an enemy of Lennart’s way of doing things and I’m not the least bit ashamed to say so (long and loud) as I listen to flawless playback via Esound (esd).
PS: Stop writing comments saying it’s all fixed and magic now. It’s not. If you think I’m wrong. Wonderful, write your own blog entry about what an idiot I am.
