Not really sure what is going on, but looks like an OpenAL-alsa-Pulseaudio problem. AL lib: alsa.c:388: Could not open playback device 'alsa': No such file or directory SND| alc_init: success, using OSS Software Maybe better to set OpenAL to use OSS directly with "drivers = oss". With "drivers = pulse" 0 ad will not start at all (black screen). There is a bug track here suggesting to upgrade alsa. I will try later. Edit: No I will not try. As far as it works really well with the "drivers = oss" there is no problem.

Ok solved problem with crackling. Crystal clear sound now all the way. following this guide:

Hello all. My first post on forum I also have problems with sound and popling/crackling using Ubuntu (Karmic). First I got error: bt_audio_service_open: connect() failed: Connection refused (111) popling/crackling and then no sound. Also I got low fps problem running the game. I did: sudo apt-get install libasound2-plugins padevchooser libsdl1.2debian-pulseaudio sudo apt-get purge bluez-alsa After reboot sitation is a bit better. I got rid of the "Connection refused (111)" message and low fps complaints. The sound is still crackling but it does not shut down. Also the sound becomes clear if I do nothing, and if I for instance click a unit crackling starts. (?) I am not familiar with 0 A.D. and do not know how the audio pipe goes (sdl? connection to libasound2.so?). So stumbling and try to learn Please bear with me.... Guess the "bt" in "bt_audio_service_open" refers to bluetooth?
