Mixer for simultanous playback of mp3 files and line-in signal

[splato]

Hi

I have an iriver H340 with Rockbox 3.0 installed.
I want to use the line-in to plug my guitar multieffect device (Digitech Rp80 without Aux/line-In) into the iriver and play along with mp3 files. Is this possible?

No, this isn't supported. But if you're not interested inrecording, just the playback and mixing, it should be possible to reconfigure the audio chip to do the mixing for you. Recording the whole thing is out of the question...

Hi!

Oops my post was moved to "Recording"-Forum, but I just wanna mix line-in and music playback in my iriver H340 for playing along with my guitar. That would be great.

Guitar-->RP80-->H340-->Headphones :-)

I'm not interested in recording things that way ;-)
