[Bug 429373] Re: Sound is stuttering using libsdl1.2debian-pulseaudio and alsa packages.
In the latest version of dosbox (tested on raring), the rate seems to be set to 44100 and prebuffer to 20 by default everywhere. Can anybody experiencing this problem check if it's being resolved? As a side note, uninstalling any pulseaudio package is not a good solution but just a temporal workaround. It is the sound server used in ubuntu in the default installations. ** Changed in: dosbox (Ubuntu) Status: Confirmed = Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/429373 Title: Sound is stuttering using libsdl1.2debian-pulseaudio and alsa packages.

Hello. I'm expirienced similar problems with alsa output of dosbox. I had tried to switch to different outputs and found out that with pulseaudio or oss output sound more-less normal, but it remains behind it should be at half of second or so on. When using alsa output, along with stuttering, sound also remains behind is should be at second or two or so on. -- Sound is stuttering using libsdl1.2debian-pulseaudio and alsa packages. https://bugs.launchpad.net/bugs/429373 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
[Bug 429373] Re: Sound is stuttering using libsdl1.2debian-pulseaudio and alsa packages.
For anyone who wants to have usable DOSBox without multiple hacks - removing PulseAudio helps (otherwise You don't have true ALSA but only PA's ALSA emulation which supports only ~ 70% of ALSA specs). And ALSA in Karmic even supports hardware mixing so you don't need to install esound. PA causes so many problems these days, still.

[Bug 429373] Re: Sound is stuttering using libsdl1.2debian-pulseaudio and alsa packages.
Hi, Setting all the rates mixing rates in dosbox.conf to 44100 instead of the default value 22050 will decrease the intensity of the stuttering and sound glitches (confirmed by me and Michał Gołębiowski). This is probalbly As Adam told us in the last post. I can confirm that increasing the buffer in the config file will reduce problems even further (to a near perfect situation). Tested with 'dunemidi.exe' Adlib playback program and 'lotus.exe' from Lotus - The Ultimate Challenge. Are there any buffering differences between the esound and pulseaudio SDL libraries as the pulseaudio driver apparently needs a bigger buffer to work properly? Note: Dosbox 0.73 does not create a config file unless you tell it to (by typing config -writeconf). I have included my dosbox.conf file. It is optimized for use with the libsdl1.2debian-pulseaudio package. All the playback rates are set to 44100 and the mixer buffer is set to 50ms instead of 10ms as Adam recommended. ** Attachment added: Dosbox configuration file.

@Vidar Waagbø I can confirm this workaround, setting rate to 44100 sort of helps (many of my apps, like Lemmings, don't have sound but I'm not sure when I run them last time, so...). -- Sound is stuttering using libsdl1.2debian-pulseaudio and alsa packages. https://bugs.launchpad.net/bugs/429373 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
[Bug 429373] Re: Sound is stuttering using libsdl1.2debian-pulseaudio and alsa packages.
Hi, I've just upgraded to karmic and, while I had perfect sound in dosbox 0.73 on Jaunty, now I have crackling sound with the same dosbox 0.73. I tried different libsdl outputs and I found out that libsdl-pulseaudio is actually way better for me than libsdl-esd. Esd output is more crackled and has much more latency. I also tried removing pulseaudio completely and using libsdl-alsa, but the result is very similar to using libsdl-pulseaudio with pulseaudio running. So I guess we have two problems here: 1) libsdl-esd is broken in comparison to libsdl-pulseaudio (bad sound quality and high latency). 2) dosbox sound is somewhat broken on karmic, independently from pulseaudio ou sdl. I also did some tests unrelated to dosbox: I tried running sdlmame on the same computer (the common point being SDL, of course). If I try a CPU-intensive game, I can have the exact same problem with crackling sound, but I don't see much difference between libsdl-pulseaudio and libsdl-esd. I also tried Odd (http://happypenguin.org/show?Odd), a game using SDL, and I get perfect sound with libsdl-pulseaudio, but crackling sound with linsdl-esd.

Hmm... a possible workaround, but not a satisfactory solution. DOSBox is fully capable to run DOS application wich ouputs a samplingrate of 44100 (CD quality audio). Is this a problem with the way DOSBox handles audio or is it perhaps a problem with the SDL/Pulseaudio plugin (I've only been able to reproduce this using dosbox + libsdl1.2debian-pulseaudio, other applications works fine with the pulseaudio lib)!?! -- Sound is stuttering using libsdl1.2debian-pulseaudio and alsa packages. https://bugs.launchpad.net/bugs/429373 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
[Bug 429373] Re: Sound is stuttering using libsdl1.2debian-pulseaudio and alsa packages.
For those who want to stick with pulseaudio, reducing the mixer's rate in the dosbox.conf file often fixes this problem. If the dosbox.conf hasn't been created already, run dosbox and type config -writeconf dosbox.conf into the prompt. This should create a /home/username/dosbox.conf file. Open it and scroll down to the line that says rate=22050 and change it to rate=11025 or something lower like 8000. -- Sound is stuttering using libsdl1.2debian-pulseaudio and alsa packages. https://bugs.launchpad.net/bugs/429373 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
[Bug 429373] Re: Sound is stuttering using libsdl1.2debian-pulseaudio and alsa packages.
Here's what I'm experiencing (I think it's the same bug but not sure): The sound works fine *except* every 3 or 4 seconds, it speeds up to a high-pitched speed for a tiny fraction of a second. This creates a high- pitched click sound on what is otherwise normal. This is in Jaunty, package version 0.72-1.1build1. Also affects a source build from upstream 0.73, but only on Ubuntu (works fine for me in Windows). I can't figure out how to change between libsdl1.2debian-pulseaudio and libsdl1.2debian-esd (as recommended in the above report).
