I have a really strange problem with dropouts while listening to AAC+ streams…
The AAC stream from Radio Swiss Classic will play all day if the wifi adapter happens to connect over 2.4GHz 802.11g (at about 70Mb/s). But if I connect at high speed over 5GHz at a 433Mb/s bitrate, AAC+ streams drop—sometimes in seconds, sometimes in minutes. Sometimes it hangs for ten or twenty seconds and comes back, other times it never comes back.
I am using and Edimax AC600 wifi adapter using a driver I installed on top of Volumio. I tried upgrading to a faster SD card—didn’t help. I use the faster 5GHz network to play back DSD64 files without popping. Other than this issue, it works well.
I’m pretty sure the culprit is mpd. I looked in the mpd log file—nothing strange seems to be going on.
