I dont get it. How to monitor a nonblockig socket in a correct MPD style? Idea is to implemenent a mixer plugin for Sonos. Plugin should discover and control Sonos devices: set MPD http server as Sones input, volume and mute control. My question is how to manage nonblocking tcp socket io with MPD. A...

Maybe usefull for someone. Installing Ambians firmware package for Banana Pi (and reboot) fixed choppy audio. Not able to get rid of hum and corrupted SD cards. My little adventure ended with a twelve year old fanless 1.3 GHz Celeron mainboard from scrapyard (Debian testing i386 - old board) and ext...

As Max stated above try to disable resampling in mpd.conf.

Code: Select all

resampler {
	plugin "libsamplerate"
 	type "Fastest Sinc Interpolator"
	enabled "false"
}

Not directly related to MPD but maybe someone has useful ideas. Hum: Banana Pi M1 with recent Armbian Buster is connected from internal audio to old late 70s Sony stereo (3 pin power connector). MPD from git uses ALSA output. When MPD plays no sound there is a quite loud hum. Hum goes away when MPD ...

ncmpc (local or remotehost) should to the trick. Or canata - on headless server of course remote only.

or https://www.musicpd.org/doc/mpc/html/ but mpc is useful for scripts. Getting started with MPD use ncmpc for commandline or cantata for graphical user interface.

And now for something completely different (at least its audio related). Anyone using Dante (Audio over IP, AES67 RTP) gear?

Nowadays, streaming is synonymous with playing music on a PC. I like MPDs streaming feature capabilities for Sonos, Chromecast Audio an maybe other hardware. Adding some more features would be cool eg keep multiple outputs in sync, adding and removing outputs during runtime, routing audio and of cou...

But there's also the class "IPv4Address" which is implicitly convertible to "SocketAddress", and that class may be easier for you to handle. It can be initialized with a "struct sockaddr_in", but can also be initialized with IPv4 octets plus port, no fiddling with big-endian. That's how it worked. ...

Maybe stupid question but I do not get it. Want to send an udp datagram to multicast address using MPD's internal API. SocketDescriptor MySocketDesc; if (!MySocketDesc.Create(AF_INET, SOCK_DGRAM, IPPROTO_IP)) { // error } Ok there is a socket descriptor. But MySocketDesc.Write() requires SocketAddre...

Roughly 35% faster. I am impressed

I use one MPD, which serves one stream up to five local clients. Not five different streams. If you want to access your music from the internet use appropriate software, eg Ampache. With all my deep respect to the MPD project: MPD is NOT well suited for your intended purpose.

@Huecuva> Maybe you should describe functionalities rather than name programs. Where are the music files stored? Wired LAN or Wifi? Where should the sound be played? Where is playback controlled? Max is always a bit skeptical about the http streaming capabilities of MPD. In my experience, up to five...
