    You can change the order, see alsa docs. IIRC module param index=foo.

      Hence "mostly". For the record, I've never had any issues with Flash on PulseAudio (although I don't use Pepper), or native games on PulseAudio (there were a few snags with Wine, although there were even more snags with Wine without using PulseAudio). There was one problem with Skype recently (but with a well-documented workaround). And I had issues with VLC, but then I switched to MPlayer2 and never went back, so I don't know if those issues are still there (and that is due to my sound card drivers being not very up to snuff).

So is it still like that you have to fiddle around to get such apps working with sound correctly? (honest question)
        exactly, and is not my soundcard, because I tried with a via vt, a realtek and soundblasters cards, but every card have problems, is so depressing.

          If I wanted to fiddle with my PC, I'd use Windows!

            This is exactly why pulseaudio rocks. You can't even find proper documentation for setting up ALSA. My laptop also had issues and played sound via HDMI only when using standard ALSA. I couldn't figure out any way to fix it and read tons of forum posts. After installing Pulseaudio everything started to work, even volume sliders. Latency is not bad. At least less than 50-100 ms for me.

              Probably 40% of users have Intel HDA nowadays.

                Wired has cables which cost money. People spend three to four figure numbers in cables in some communities. When it comes to remote wired audio, only analog scales. The other protocols are expensive and often lossy. Airplay has huge lag, Pulseaudio remote audio might not work.

                802.11n has 1-5ms latency but easily supports 100 Mb/s while FLAC audio is 0.7 Mb/s. Quality is good. No background noise unlike in SPDIF which is lossy and can react to room light. You can decrease transmit power and it's already within safety region out of the box.

                  For the record: I don't think that PA rocks. I just prefer it over config file hunting and editing (and anything offered by Windows which doesn't even output any sound on my laptop without manually downloading and installing the drivers *blarg* [same for WiFi, power management, etc.]).
                  If I had migrated directly from Windows to Linux, I might have endured enough pain to cope with shit like editing config files but I migrated from OSX.

                    Hi,
                    could you tell me if pulseaudio 5.0 will help me:
                    I use PA to stream audio from my ubuntu x64 13.10 (PA 4.0) to raspberry Pi. It works, but very often PA has strange interaction with flash player (www.deezer.com / www.grooveshark.com)
                    let me explain:
                    I start playing musing on my desktop: sound is OK on local speakers
                    I switch audio output to the networksound card on RPi => player hangs and stops playing, no sound
                    If I switch back to the local sound card => the player go on and the sound is back
                    Any ideas?
                    Thanks

                      It's a known issue. I have it too. Switching playback to remote sound card hangs. Both PA's own protocol and airplay.

                        You can blacklist the drivers for the "wrong" sound card

                        I don't know if you can do this on your laptop without killing your video driver, but in many cases you can get around a "wrong soundcard" default by blacklisting the driver for it. I had that problem on a Pentium 4 in which I had dropped an Nvidia GT520 with the blob to play 1080p video in VDPAU, causing the sound to default to an Intel device that did not work. Blacklisting that driver made the installed sound card come up first. On a laptop with AMD and open AMD drivers, HDMI sound can be disabled in the video driver itself. Don't know what the Nouveau situation is on that.

                        Pull up the output of dmesg, look for your soundcard drivers. If the HDMI shows any driver other than your video driver, blacklist it in /etc/modprobe.d and reboot. Now the sound you want to use is the only soundcard and should come right up

                            One of the cool things about PA is that you can redirect sound sources to whatever device, on the fly! You can't even do that in Windows. Well, maybe you can in 8 but I haven't used 8 yet. Did you not install the apps like Pulseaudio Manager or Volume Control? You can use Volume Control to send your Flash audio to either card or devices on the card (like analog or optical). KDE Kmix will also redirect audio to specific devices. On the other hand, I have three devices (onboard Intel HDA, a PCI HT Omega Claro Halo card, and the HDMI on my video card) and I have to configure PA manually because to this day it will not add the Claro Halo or the HDA digital outputs to the list of devices by itself. Grrr.

                              Pulseaudio seems to be maturing nicely-and good for grabbing web audio

                              I reinstalled Pulseaudio in my main system today due to a new use case: Recording the output of the sound card when the hardware does not support recording the "mix" output.

                              On my big 8 core, Pulseaudio 4.0 shows less CPU use than Cinnamon does, sometimes less than X. We don't have Pulseaudio 5 yet, looking forward to it. I made once change to version 4: changed "autospawn" from "yes" to "no" in /etc/pulse/client.conf so I could turn it on and off. Cinnamon's volume control applet will show up when it's running, disappear when it's not as an indicator of pulseaudio's status. I then found that the old issue of audio stutter when playing 1080p AVCHD clips in Kdenlive seems to be entirely gone, and since I didn't get a boatload of pulseaudio CPU use this should be true on the 4 cores as well. If not, I can turn it off until I am done with that job.

                              The pavucontrol package gives a really nice GUI for controlling Pulseaudio-including the ability to record from the mics or from the output, which busts any and all attempts by webhosts like Google to control recording sound from the Web. Now no publisher of some news video I need a clip from can defeat the combination of gtk-recordmydesktop, Audacity, and pulseaudio, at least not without going to outright DRM that in my case means it's entirely blocked. If I can stream it, I can grab it. For that matter, I don't think ANY of the cross-platform DRM schemes that are denied a "protected path" on the bus could defeat the screen grab-audio output monitor combination anyway.
