Setup: ATV2 -> OPTICAL OUT -> DAC -> 2.1 SPEAKERS
XBMC audio output: Analog, Optical/Coax (both settings tested, same results)

Problem: During normal music playback, when advancing from track to track (either because playing track has ended or by pressing skp fwd), the crossfade is imperfect (often occurring with milliseconds of silence and/or a pop), and then XBMC loses the volume control setting and next track plays at full volume (regardless of setting). From this point, skipping tracks forward or around sometimes restores the [lower] set volume but problem reoccurs after letting a track play through and then advances to next.

Problem occurs with XBMC set to Analog, Optical/Coax, ReplayGain on or off, crossfade on or off. Problem has existed on all nightly builds to date since ATV2 Frodo nightlies resumed. Problem does not exist on Eden.

Any developers aware of this? I use XMBC mainly and daily for music playback so I'm stuck on Eden for the time being. Further to that, I'd be particularly happy to help developers test audio/music library functionality being worked on in Frodo if there is ever something you guys would like focus on. I'm excited about Frodo because there seems to be a major focus on audio and the music library -- my XBMC music library is 110K+ tracks 7K albums (which means slow library loads, so I'm always happy to read commits that address improved music/library functionality).

Let me know if the posting of any logs would help in regards to this problem.

FYI, another thing -- rescanned my music library using recent Frodo builds (which takes about 24-36 hours!!) and after completion no COMPILATIONS button/category appears in the music library though there are 700K compilations properly tagged in my collection.

Thanks for any input.

No we were not aware of this. Thx for reporting. I can reproduce the volume goes wonkey after track change. No time left for today and the next days though.

For the cross fade i can already tell you that you shouldn't expect a quick fix for this. We are still struggling with the new audioengine which was introduced in may.

Crossfade is no big deal while playing with Frodo nightlies, I understand the audio framework is all new.

The eventual volume fix will be nice though as Frodo isn't very usable for continual music playback currently.

FYI, the volume problem has resurfaced on the 8-14 nightly.

The volume spike should be fixed.

I tried the latest nightly and occasionally I still have the volume spike on track transition...

I don't have crossfade enabled, and use audiophile = 1...

I'm going today to vacations, so I can't help right now...

Volume spikes and then it gets low again right? If so its a known issue for now - didn't find the cause of it yet.
