PeppyMeter and moOde

I've installed enough of the PeppyMeter infrastructure to exercise its use of the ALSA loopback path., e.g., I've got everything but the virtual meters themselves.

I can confirm that trying to play the AAC-encoded M4A tracks I downloaded from iTunes with ALSA loopback enabled results in a failure internal to the MPD subsystem. MPD aborts, which leads to the error message you originally reported. The same tracks play without issue if ALSA loopback is disabled. 

[ETA this hypothesis may be bogus. See following post.] My current hypothesis is that this failure is triggered by the way the coverart is embedded in the M4A container.

The same result occurred with a different M4A track I'd obtained elsewhere, also AAC encoded and also with coverart encoded as a stream in the M4A container. Hence, I can't attribute the failure to practices at iTunes   per se.


It's going to take some more detective work before I feel comfortable passing this issue to devs outside the moOde project.
