The alsa/sdl crackling issues were fixed in libsdl 1.2.14, which is in lucid, so I will close this bug.

Ryan - not 100% sure this is the bug I should be looking at, but I seem to have a similar crackling noise when viewing flv files in Totem. First thing I tried was your SDL-1.2 branch. Previously, pausing and playing the file would remove the crackling - so it wasn't always present (hence my reason for suspecting this bug may not be my issue). Regardless, using a screencast downloaded from http://screencasters.heathenx.org/wp-content/videos/ep070/ep070.html as my test file, it crackled like crazy, pausing and playing several times would occasionally remove the crackle. After applying the latest from svn, it appears that the crackle is still there but the pausing and playing seems to be more successful, less likely to hear the crackle than not. It also sounds like the crackle starts for a nano second but then stops in many cases when resuming playing the file. Apologies if this is a red herring, just haven't seen any follow ups to your request so I thought I'd give it a go. ** Attachment added: alsainfo.txt http://launchpadlibrarian.net/34042003/alsainfo.txt -- Sound crackles snaps when SDL volume not set at 100% https://bugs.launchpad.net/bugs/66483 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

We believe (but aren't sure) that there are two issues here, and both are in SDL itself, not the games, SDL_mixer, or ALSA. Those that are so inclined, it would be useful if you would update to the latest subversion of SDL 1.2 and see if it fixes the issue. svn co http://svn.libsdl.org/branches/SDL-1.2 cd SDL-1.2 ./autogen.sh ./configure make sudo make install (you'll need the appropriate -dev packages, but if you don't know what that means, you should probably let someone else test instead.)

Still no solution for this problem, however there -is- now a viable workaround. In Hardy, the standard sound server is meant to be PulseAudio, and so far from my experience it isn't bad. I say meant to be, if you've upgraded from Gutsy you probably have to follow these instructions - https://wiki.ubuntu.com/PulseAudio . The key is the package libsdl1.2debian-pulseaudio, which replaces libsdl1.2debian-alsa. Set up PulseAudio according to the instructions, get this SDL package, and there's no more crackling. Even if you fiddle with the volume. Of course, this doesn't address the issue for people who don't want a hulking great sound server and just want the bare-bones ALSA plugin to work as it should.

Maybe this bug is not that important at all? For Hardy Heron, Ubuntu may be heading to Pulse Audio as universal solution [1]. I tried pulseaudio on my Ubuntu 7.10 PC, it works nice (there are instructions how to do it [2]). Pulseaudio emulates esd very well, because it is a replacement for esd. So I asked SDL to output sound via ESD, by installing package libsdl1.2debian-esd. My speakers aren't very good but what I hear sounds OK or at least much much better compared to crackling sound via alsa. Probably thanks to pulseaudio, latency is also very good.

Another Neverball contributor here. After a couple of unsuccessful attempts to locate a good version of SDL_mixer, I gave up and switched my attention to SDL. (Note: I'm using Debian, but I am aware that this issue also occurs on various other operating systems and should be treated as such.) There are old libsdl1.2 Debian packages available at http://snapshot.debian.net/package/libsdl1.2. By using dpkg to downgrade the libsdl1.2debian-alsa package, I quickly managed to locate the last known-good version, which is 1.2.7+1.2.8cvs20041007-5 (trailing 5). The version right after this one, 1.2.7+1.2.8cvs20041007-5.1 (trailing 5.1), has the problem. My understanding is that the upstream sources used for both packages are identical. Locating the cause of the issue should be a matter of looking at the diff of debian subdirectories of those packages by a person familiar with SDL and Debian packaging.

Hi, I'm one of the SDL_mixer developers. Just to be clear about tracking this down, can someone do this before running the game: export SDL_AUDIODRIVER=sdsdfsdf ./the_game_I_want_to_run You should either get no audio or the game will fail or something. We're just confirming that the SDL_AUDIODRIVER parameter is being noticed. Now try this: export SDL_AUDIODRIVER=alsa ./the_game_I_want_to_run ...and see what happens. That will be SDL talking directly to ALSA for audio output (libasound, specifically). Then try this: export SDL_AUDIODRIVER=dsp ./the_game_I_want_to_run ...that's SDL talking directly to /dev/dsp (alsa's OSS emulation). See what happens. I want to determine if it's a driver issue or our use of alsalib. Also, if anyone has programming experience, is it only causing a problem if Mix_MusicVolume() is changed in these games?

[Bug 66483] Re: Sound crackles snaps when SDL volume not set at 100%
Hi ryan, Thanks for taking the time to help us track this down. Setting SDL_AUDIODRIVER to jibberish does cut off the sound, so the parameter does work. Setting it to alsa works, but with fuzziness. Setting it do dsp removes the fuzziness, but then there is the downside of using OSS instead of ALSA. I'm downloading the source of Neverputt as I write this, and I'll post back if it seems like Mix_MusicVoulme is causing this. So, with your results, we have two possible sources of the problem: 1) SDL_mixer crackles when Mix_MusicVoulme is not at 100% and is using ALSA. 2) ALSA crackles when the volume is not 100% (although non-SDL apps seem to work fine, so I kind of doubt this). There might be a third problem, but I don't see it yet. Correct me if I'm wrong.

Argh, my comment got eaten. Anyhow, the gist is that it's possible that SDL_mixer's volume routine is buggy and happens to be working when adjusting the audio for OSS's device format, but not the data format ALSA is expecting. Can those having problems please compile the above attachment and run it a few times: You'll need the compiler tools (apt-get install build-essential, I think) and the SDL development package (apt-get install libsdl1.2-dev, I think). Compile it: gcc -o test-sdl-audio test-sdl-audio.c `sdl-config --cflags --libs` Run it: SDL_AUDIODRIVER=assdf ./test-sdl-audio SDL_AUDIODRIVER=alsa ./test-sdl-audio SDL_AUDIODRIVER=oss ./test-sdl-audio Then please post the output from all three runs to this bug report. The first run will produce an error, that's okay, it's just a sanity check.

I downloaded neverball so that we can compare apples to apples here, and I ended up with similar results as Jacob. 'SDL_AUDIODRIVER=dsp neverball' results in crystal clear sound; however, 'SDL_AUDIODRIVER=alsa neverball' results with the static problem. The static problem consists in music playing staticy when not at 100% in- game volume; it plays crystal clear at 100% volume. Also, sound was slightly staticy at ANY volume. It is less staticy than the music is though. It was more obvious after I turned off the music and cranked up my speaker volume. Again, there is no static at all with oss/dsp. -- Sound crackles snaps when SDL volume not set at 100% https://bugs.launchpad.net/bugs/66483 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 66483] Re: Sound crackles snaps when SDL volume not set at 100%
I was looking at the alsa code this evening and noticed that putting the following line into ~/.asoundrc should be a workaround for my issue: defaults.pcm.dmix_max_periods -1 It seems to have solved the problem without any side effects, but only for some applications. Without this option, supertux is staticy, yet with it, it isn't. However, rott is just as staticy with this option as without. I don't really understand the alsa code enough to truly grok this option's implications. If you find that it resolves some issues, such as with supertux, it might be worth posting in the alsa bug thread that I started. -- Sound crackles snaps when SDL volume not set at 100% https://bugs.launchpad.net/bugs/66483 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Whether it's a driver issue or a userspace issue remains to be resolved. Does enabling slowptr for dmix explicitly resolve the symptom?
