It handles sound input from esound/arts/ALSA/etc and does fancy mixing and transporting and generally makes sound support totally awesome. You can get more info about it here: <a href="http://fedoraproject.org/wiki/Releases/FeaturePulseaudio">http://fedoraproject.org/wiki/Releases/FeaturePulseaudio</a> Since it's a replacement for esound/arts, it's started when you log in to GNOME/KDE, just like those programs were. Here's the problem: Skype apparently still doesn't know how to use ALSA properly. Since it's a closed-source app there's not a lot we can do about that. There appears to be a workaround mentioned here: <a href="http://developer.novell.com/wiki/index.php/Feisty/HOWTO:_PulseAudio#Running_Skype">http://developer.novell.com/wiki/index.php/Feisty/HOWTO:_PulseAudio#Running_Skype</a> Basically, try running: "padsp skype" and PulseAudio will emulate the OSS interface to make skype happy.</blockquote><div> I've found that my problems go beyond just skype problems. After the latest update, arecord doesn't work. It creates a 44 byte file that looks like what used to happen when I had capture disabled. I used to run alsamixer to fix this, but now alsamixer has fewer controls and shows "PulseAudio" as the card and chip. It used to show "HDA Intel" as the card and "SigmaTel STAC9200" as the chip. According to this new alsamixer view, capture is enabled, but arecord doesn't work. system-config-sound fails to play a sound now unless I kill pulseaudio first. And after I kill pulseaudio, arecord fails entirely. Is there a way to disable pulseaudio or otherwise fix this problem. I have no working mic anymore. :( David PS - Here is a before (when my audio worked) and after (now, when arecord captures a 44 byte file): Before: Simple mixer control 'Master',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 23 [74%] [-12.00dB] [on] Front Right: Playback 23 [74%] [-12.00dB ] [on] Simple mixer control 'PCM',0 Capabilities: pvolume Playback channels: Front Left - Front Right Limits: Playback 0 - 255 Mono: Front Left: Playback 191 [75%] [-12.80dB] Front Right: Playback 191 [75%] [- 12.80dB] Simple mixer control 'LFE',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined Playback channels: Mono Limits: Playback 0 - 31 Mono: Playback 31 [100%] [0.00dB] [on] Simple mixer control 'Capture',0 Capabilities: cvolume cswitch Capture channels: Front Left - Front Right Limits: Capture 0 - 15 Front Left: Capture 10 [67%] [15.00dB] [on] Front Right: Capture 10 [67%] [15.00dB] [on] Simple mixer control 'Capture Mux',0 Capabilities: volume Playback channels: Front Left - Front Right Capture channels: Front Left - Front Right Limits: 0 - 4 Front Left: 0 [0%] [0.00dB] Front Right: 0 [0%] [0.00dB] Simple mixer control 'Digital',0 Capabilities: cvolume Capture channels: Front Left - Front Right Limits: Capture 0 - 120 Front Left: Capture 68 [57%] [4.00dB] Front Right: Capture 68 [57%] [4.00dB] Simple mixer control 'Input Source',0 Capabilities: cenum Items: 'Mic' 'Front Mic' 'Line' Item0: 'Front Mic' After: Simple mixer control 'Master',0 Capabilities: pvolume pswitch pswitch-joined Playback channels: Front Left - Front Right Limits: Playback 0 - 65536 Mono: Front Left: Playback 49934 [76%] [on] Front Right: Playback 48623 [74%] [on] Simple mixer control 'Capture',0 Capabilities: cvolume cswitch cswitch-joined Capture channels: Front Left - Front Right Limits: Capture 0 - 65536 Front Left: Capture 65536 [100%] [on] Front Right: Capture 65536 [100%] [on] amixer used to report </div></div>
