Hi.

Hello Alexander!

I have cloned the raop2-v2 branch from
https://github.com/colinleroy/pulseaudio

First, thanks for the testings.

The following test was applied.

I have installed the "Android HiFi" application (also known as "HiFi
Speaker"), version 1.7 Beta, on my Android phone, and started it.

Link: http://forum.xda-developers.com/showthread.php?p=29986442

Version is important: this one is possibly-buggy in an interesting way.
Also, newer versions require a license for more than 30 minutes of
playback. Note: for some reason, Google Play has removed this app, so
you can only get it from various shady sources such as above.

Then, I ran the following command:

pacmd load-module module-raop-discover

Result: it found the speaker!

Then I started mpv on a music file, and redirected its output to the
HiFi Speaker using pavucontrol. Result: it worked.

Then I pressed the back arrow to seek back. Result: it froze.

I can reproduce that, will try to fix it. You should not experience such
a problem with GStreamer based players, I think. Have you try any other
players?

Also tested with VLC, seeking there does not freeze.

With Bino, I was able to trigger this assertion failure:

I had no GStreamer-based players installed, so installed gst123 for a quick test. Result: same freeze. E: [raop-sink-[192.168.1.39]:5000] rtsp_client.c: Assertion 'c->url' failed at modules/rtp/rtsp_client.c:441, function rtsp_exec(). Aborting.

Then I killed the HiFi Speaker application on Android. Result:
PulseAudio unfroze mpv's stream and moved it back to analog headphones.

Then I started Airfoil Speakers on Android. Result: PulseAudio does not
see it, even if module-raop-discover is reloaded.

This may be a module-raop-discover bug (Avahi related). Can you post the
full pulseaudio log?

Sure. And here is what "avahi-browse --all" prints:

aep@aep-haswell ~/raop/pulseaudio $ avahi-browse --all


The relevant part of the pulseaudio log is:


D: [pulseaudio] socket-client.c: connect(): Connection refused
E: [pulseaudio] rtsp_client.c: Connection failed: Connection refused

So - it is not on port 5000. This connects and pretends to send audio:



protocol=TCP causes Airfoil Speakers to crash.
