adelias Wrote:I'm getting some stuttering on multichannel hi-res audio, have you changed any settings in your .mpdconf for the hi-res profile?

I have custom mpd.conf file for each profile - each output is via a different ALSA output. I am away from home now so I can't post my conf files, but if you post the output section of your mpd.conf along with your ALSA conf so that I can take a look, perhaps I can help.

IMO The first thing you should do is make sure mpd bypasses the mixer and sends audio straight to your output. In your mpd.conf:

Code:
mixer_type "disabled"

Thanks! That option fixed the stuttering. I had already commented out all the mixer options in mpd.conf but apparently that wasn't enough.

Yeah..the default action for mpd is to use the mixer. You have to tell mpd specifically not to do certain things. Commenting out options or settings doesn't always have the expected result.

With the higher bitrate (24/96, 24/192) multi-channel lpcm files I'm still getting a bit of buzzing and dropouts on all speakers.

/etc/asound.conf
Code:
pcm.!hdmi-remap {
type asym
playback.pcm {
type plug
slave.pcm "remap-surround71"
}
}

  slave.pcm "hw:0,3"
  ttable {
    0.0= 1
    1.1= 1
    2.4= 1
    3.5= 1
    4.2= 1
    5.3= 1
    6.6= 1
    7.7= 1
  }
}

~/.mpdconf
Code:
audio_output {

Try this: Set your mpd audio output to the hdmi-remap pcm and see what that does for you. As per below.

~/.mpdconf
Code:
audio_output {
        type            "alsa"
        name            "HDMI"
        device          "hdmi-remap"        # optional

##      mixer_control   "PCM"           # optional
##      mixer_index     "0"             # optional
}

Yep, that did it. Its working great now. Thanks again!

Izoubek, nice job on the album art fetching from allmusic.com. Any plans to allow use of folder.jpg file for album art?

- Balthazaar - 2010-12-19

Album art? I don't see that option...

- adelias - 2010-12-19

Its included in the latest builds from the git repository.

- Balthazaar - 2010-12-20

Got the latest from git. I see the options and have selected them, but there is no album art shown. Where does MPDClient save the art?

- adelias - 2010-12-20

I haven't enabled saving album art but it should display art if its available at allmusic.com.

Thanks, hope you guys like it. Forgot to announce it here.

I am still testing fetching. If an image is not fetched, there are 2 possibilities.
  1. Album image is not available on allmusic.com
  2. There is an error in my regex when searching for it, please report album and artist name, if you find such.
I am not sure how would be implemented displaying from folder.jpg That is because I use MPD protocol to display directory structure and artists etc. I have no idea where the files really are (since MPD is providing something like vfs) and this would never work if you do not run it locally. Hmm .. just writing these lines, it would be possible, I'll think about it :-) I would add new setting for setting up path to your music and than search for folder.jpg in path+currently played filename's parent dir.

These days I am thinking about redesigning UI. I'd like to do tabs above content instead of list of button. Content area would be wider than. On the other hand, where to put album art images? What do you think?

Files go to ~/.xbmc/userdata/addon_data/script.mpdc/albums

I think tabs would be good idea. Something like this maybe? is that what you had in mind?

Perhaps I made a poor choice of album artwork for this example. Smile

I also must say I don't like the info currently displayed in the bottom LH corner Artists/Albums/Tracks/DB Time. I think it clutters an otherwise 'clean' screen. Any possibility of making this info display an option?

Thanks!

Exactly. Something like that.

You're right. I just wanted to show these stats. I'll get rid of it or maybe make the profile name to work as button, which will raise these stats.

Btw your choice is very very good, don't care about album image. OSI always gives me good energy. Really good stuff. This reminds me, I've almost forgot to listen to it last days ... :-)
