Decode AAC streams with mpd-full package

Hi. I'm using mpd on OpenWrt to listen web radio streams. MP3 streams work fine, but I have problem with AAC streams. Some o them plays with sound distortions, and some generates only noise sound.
I found that if I install ffmpeg package and disable faad plugin in mpd.conf, AAC streams play fine for few seconds, then I get stuttering sound. Is any way to decode AAC on router properly? I'm running mpd on MT7621 (Netgear R6220)
