Regardless the issue doesnt happen at all when I use Alsa, so same configuration, only difference is no pulse and it works perfectly. So it's not the receiver, it's pulse.

    The fact is that when I don't use pulse everything works perfectly and I like it when everything works perfectly.
    Pulseaudio defaults to 44.1k. You can set it to use 48k by default in your /etc/pulse/daemon.conf

      Obviously that's just some other buggy crap. Well, I guess sooner or later it will get pulled into a stable release.
      Yes, the multimedia repo is for development. It feeds into Factory.

        BAM, this is what I call the truth...there are true Windows fanboys pretending to be into Linux but they whine when something doesn't work when they don't know the configuration of it.

          Well this is an interesting topic. In this scenario I can see one of two things happening. On one side you have an output and on the other side you have input. In my case the output is a c-media 8770 optical SPDIF. The input is a sony 7.1ch surround sound reciever. What format should the output device be, and what format does the input device expect it to be? In my particular case the sony works with PCM among a few others, I just use PCM. The cmedia card also supports PCM and it seems to work properly with Alsa. I've watched movies that I know are 48K and I've listened to music that I know are 44.1K.

          So does the output samplerate match the format of the source material, or does the sound card resample it before it gets sent to the output?

            It's just me, or PA 4 has better audio quality than before?

              Pulse audio has worked great for me for quite a while in the Kubuntu series. My biggest beef with PA is I still can't get bit perfect sound out of it. I have to use the deadbeef player and send the sound directly to ALSA for any critical listening. I wish there was a setting that I could use to not get it to mangle and resample the audio before it goes out to my speakers.

                It seams that its incompatible with bluez5 or not?

                  The "TODO" List for Pulse 5 seems to IMPLY that its incompatible with Bluez5. But it may be an issue of "We're compatible, we're just not taking advantage of the features of Bluez5"

                  EDIT: Fixed typo in bold.

                    Hmm cause Arch doesn't build it with Bluez5.

                      Fixed a rather important typo in my earlier comment, Thaodan.

                        ALSA may also resample sound. My sound card doesn't support 44K, so ALSA has to resample everything to 48K.

                          So why it depends on bluez4 and on bluez-libs(bluez5 libs)?

                            I have an Asus Xonar card and it can output 44.1K, 48K, 88K, 96K, 192K and many others. When I play a 96Khz 24bit flac song, coming out of my digital output is 96Khz and 24bit. When the next song is 44.1Khz, the output shifts to 44.1Khz.

                            You are correct though, you need to have hardware support as well.

                              So what I take away from this is the best drop-in sound card to run for most scenario's as an end-user (someone who who plays lotsa music of all types, movies and TV shows of all types, and dabbles with audio at a personal consumption level) are the CMedia X-Fi equivalent cards, then? (I forgot what the chipset ID's were sorry. CMI 87xx?)

                              What about the onboardies? Are they super fine, even for output to A/V recievers?

                              AFAIKnew the audio chip's are/can be bypassed and the reciever handles the audio muxing, sampling amping etc which how it should be if you are using one!?

                              I'm personally looking in to two seperate ways to do HTPC properly, with one being a micro-HTPC set up like a RaspberryPi or even Gumstix-sized approach for car and caravan installs etc, and a traditional Mini-ITX for more grunt and permanency in the home. I am trying to minimise power use, and provide maximum support with hardware (TV's, receivers, audio and vga) and media types (avi, no4, aac, mov etc).

                                Cmedia 8770 or Cmedia 8788. I think 8770 has a better driver though. But 8788 is more capable hardware.
