Read the OP and FAQ newfriends! It'll save you time.
An entire board dedicated to h-audio: http://board.kasumi.moe/koe/catalog.html (check the sticky there as well)

>How do I find h-audio?
DLSite. Japanese site (http://www.dlsite.com/maniax/) English site (http://www.dlsite.com/ecchi-eng/)
NOTE: Not all works on the Jap site are on the English site.
Each work has a product code attached. RJXXXXXX for the Japanese site, REXXXXXX for the English site, and RGXXXXXX is a circle's code. TIP: Use the RJ product code (if using the English site, simply replace the RE with RJ) to search for a work on Google, the Baidu folder, Perfect Dark, and other sites.

>Where do I search for h-audio?
1) Google, mostly. Also try:
http://www.anime-sharing.com/forum/voice-works-129/
http://hentai4daily.com
http://hentai-d.com
http://hentaiupdate.com
http://www.vivahentai4u.net

Beware of fake sites!

PROTIP: If it needs a premium account, it's likely fake.

2) THE BAIDU FOLDER
Seems to be updated regularly. If you're searching for a recent work, there's a good chance that it's here.

More on this in the next post.
