I'm trying to rip CDs onto my computer using Sound Juicer. I've created a profile for encoding with FAAC in GMAudio Profiles with the pipelines "audio/x-raw-int,rate=44100,channels=2 ! faac name=enc", "audio/x-raw-int,rate=44100,channels=2 ! faac profile=1", and "audio/x-raw-int,rate=44100,channels=2 ! faac" . All three ways, nothing complains when I rip a CD, but playing the AAC files back with "totem /path/to/file.m4a" I get "GStreamer-WARNING **: element internal_thread claimed state-change success,but state didn't change to PLAYING. State is PAUSED (NONE_PENDING pending), fix the element" in the terminal, and Totem says it "Could not determine type of stream." iTunes doesn't like the files, either. Running "gst-launch filesrc location=/path/to/file.m4a ! faad ! osssink" (or with alsasink) gives "RUNNING pipeline ..." and then, after a while, "Execution ended after 3695 iterations (sum 296036133000 ns, average 80118033 ns, min 111000 ns, max 1723749000 ns)." I hear no sound, though, but I don't hear sound with AAC files that work in Totem. I've tried with multiple CDs, all with the same result. I would really appreciate any help I could get in figuring out what's going wrong. Also, I wasn't able to find an explanation of the options "profile=1" or "name=enc" anywhere; is there any documentation on what all the options for the plugins are and how to use them? Thank you for your help. Michael
