Solved audio lag Linux Mint 15 64bit

Ladro, even though Linux Mint is Ubuntu based there are differences between the two, some of them are great differences.

This works for Linux Mint 15 64bit with MATE,

That is unfortunate that the audio lag problem continues while using Ubuntu 13.04 32bit LTS

You need to keep experimenting with different things until one works.

Normally I killed Pulseaudio (you have to kill autospawn too), and I used Alsa instead.

But now I use an external sound card USB (soundblaster creative), and now Alsa in TDM it's not working unfortunately with this external device (i have no sound at all in TDM with pure Alsa). He works only with PulseAudio active, but I have random glichy or lag, that I can repair on fly only by exiting to the main menu, and change left with right option ("yes" or "not").

 

I'll do more tests, that's sure, I hope to find a solution :-D

Here's mine, from Mageia 3

 

seta s_dsp "/dev/dsp0"
seta s_driver "best"
seta s_alsa_lib "libasound.so.2"
seta s_alsa_pcm "front:CARD=halo,DEV=0" ***This one may be the critical one for performance, I do not remember, maybe needs to be in combo with other settings.***
seta s_libOpenAL "openal32.dll"
seta s_numberOfSpeakers "2" ***This can be very important if you leave pulseaudio enabled.
It must match your enabled speaker configuration.
If you change your card to 5.1 output, then number of speakers needs to be 6 AND the part of 's_alsa_pcm' setting which says 'front: ' needs to change to something like 'Surround5.1: ', though I will have to verify that.***

 

When I changed that 's_alsa_pcm' from 'default' to my named audio device*, I was able to leave pulseaudio alone and still have proper sound in TDM. *Though I have since set 'pasuspender' in my TDM launch path. I did have it working well without killing pulseaudio though.

 

* Use 'aplay --list-devices' to get your list of audio devices.

Mine is listed as:

card 0: halo [HT-Omega Claro halo], device 0: Multichannel [Multichannel]
 Subdevices: 1/1
 Subdevice #0: subdevice #0

So, the name of the card is what follows the card #... 'halo' in this case. The DEV setting is obviously the 'device' number.

 

...and the rest of the sound related stuff in my config:

seta s_doorDistanceAdd "450"
seta s_globalFraction "0.8"
seta s_subFraction "0.75"
seta s_playDefaultSound "1"
seta s_volume_dB "0"
seta s_meterTopTime "2000"
seta s_reverse "0"
seta s_spatializationDecay "2"
seta s_maxSoundsPerShader "0"

I've tried with these (and other) settings, but nothing changed.

 

My card it's marked "dev=MP3,DEV=0", I tried also with "front", "hw:", etc etc, in the "s_alsa_pcm" var, and a lot of other combinations, but nothing.

 

Anyway, i'll try more and more to solve this, there must be a solution B)

      Be honest: Who of you have actually finished Cuphead? This game is freaking tough! It might even be harder than Sekiro. Dark Souls is a joke in comparison to Cuphead! :-D

      Please, can we finally group the missions by year in the game menu?

      I vaguely recall someone recently complained about two-sided materials (curtains?) not getting lighting from both sides
      I just found a piece of code that's supposed to do just that
      Where was that discussed? (@nbohr1more?)

      I still play classic Doom (albeit with user-made mods and maps rather than the original campaign) on a regular basis. A game from the early 90's which has still got a healthy following in 2022. Pretty amazing.

      I'm beginning to understand why people who aren't into social clubbing "don't last long" on this project, and why it's so full of holes. When moderators are siding with bullies, by closing down threads that they derail, then I start to wonder if I should support the platform to begin with.
      I'm sure that the core development is solid, but when you're constantly tone policed and bullied, and moderators are playing into it too, then the project will just drive away talent, and replace it with socialites instead. ...and without talent, you only end up with a small skeleton crew trying to do everything themselves.
      ...so Dragofer and Airship Ballet, and all you other socialites, you win. From now on I'll just keep to myself. You'll never be able to do my work, but at least you'll be happy together, and that's what matters to you.
       
      Update
      Actually, I have to revise my statement:
      I actually messaged greebo - the top dog, I gather - about nbohr1more's outburst of insanity below, and since I haven't even heard back from him, I just have to assume that there's not a single core programmer here, who's not backing nbohr's threats. ...and that's bad.
      ...so if you're a newbie reading this, or an honest soul like ZergRush, then just slowly back out of these forums, run, and don't look back. This is nothing more than a cult posing as a game development project, using Thief and IDTech4 to sucker hopefuls in, to do work for them, while trying to cajole them into something going on behind the scenes, which apparently - according to nbohr - is something that should be hidden from the state. These people aren't programmers - they don't even understand things like how to fix the simplest bugs. All they have, is an engine, and an IP, and some sort of fascist social cult. There was some other project I saw being made in the Unreal Engine. Try joining that project. ...or start a project of your own. Anything but this asylum.
      Hopefully that was "divisive" enough for a final post, because at this point I really want people to leave this place. This project is, on a management level, just awful garbage, run by garbage people, apparently from the top down, and I'm just glad that they have a garbage place to stay, together, and hopefully forever.
