I have noticed that most resources for learning Yiddish are of a decidedly secular/conversational nature. Personally, I would rather immerse myself in the language by listening to a shiur (preferably on gemara or mussar) that's given in it. Unfortunately, such a thing does not exist where I live, and I was wondering if anybody knows of any Yiddish-language shiurim on such subjects that can be downloaded? I have stumbled across a few, but they were recorded in the middle of the 20th century and are of very poor audio quality.
Kol Avraham has Daf Yomi shiurim in Yiddish. The recordings I sampled seem to have a bit of echo, but were otherwise of decent quality.
If you want the Lubavitcher Rebbe, there's a lot of him speaking Yiddish. You kind of have to poke around but start here: http://www.chabad.org/multimedia/default_cdo/aid/591213/jewish/Jewishtv.htm http://www.chabad.org/multimedia/media_cdo/aid/1743851/jewish/Video.htm http://www.chabad.org/therebbe/livingtorah/player_cdo/ http://www.thelivingarchive.org/categories http://www.chabad.org/therebbe/sichoskodesh.htm http://www.chabad.org/therebbe/sichoskodesh_cdo/jewish/Sichos-Kodesh.htm http://videos.jemedia.org/

Apologies for the big geniza of random stuff (and for the randomness of some of these websites themselves) but that is often how you find good things, which task I'll leave to you :)
The Lubavitcher Rebbe (the seventh rebbe of Chabad) Rabbi Menachem Mendel Schneerson conducted most all of his shiurim in Yiddish. Most people have bad sentiments against Chabad-Lubavitch so you mind not find these useful to your purposes. Here's a link to them though if you're interested: The Farbrengen Series
(YouTube also has a few recordings, mostly people recording from a smartphone though.)
The audio quality in The Farbrengen Series is pretty nice in my opinion, unlike other films of the Rebbe which have horrible quality. As for the YouTube ones, you win some you lose some with audio quality.
It's not really "online," but you can hear Yiddish shiurim 24/7, maybe 24/6, over the telephone at this number: (718) 735-7333. (Numbers to call outside Brooklyn, NY are listed here.)
The audio quality is not great, and they speak fast, but you get used to it.
