issue ---- The AACDecoder could not be initialized

[biqi2]

Hi I use url=http://www.wdr.de/wdrlive/media/einslive.m3u, or url=http://somafm.com/wma128/missioncontrol.asx,all is ok, but, when i use url=http://s1.knixx.fm/dein_webradio_64.aac or url=http://ngcdn016.cnr.cn/live/gsgljtgb/index.m3u8, error almost happened which is about “The AACDecoder could not be initialized”, but that both url run in pc' broswer is successful. How to resolve it, pls help!

This is probably due to a lack of memory. Please activate the PSRAM

Thank you very much for your response. What capacity PSRAM should I use, 2MB or 4MB or 8MB?
