Volume too low

I just installed and tested my stereo audioinjector as instructed in this forum.
Everything seems to work, except the volume is too low. I have two 3W 8Ohm speakers, and whether I connect with the RCA jack or the headphone jack the volume is almost inaudible.

I have the hardware volume turned all the way up-- is there an alsa setting or something else that i am missing?

thanks for any help out there!

Older post so you may have found solution since then, but be aware that the audio available at the headphone jacks is exactly that...for headphones so a higher impedance load is required...16 to 50 ohms or so. The audio at the RCA plug outputs is line level and cannot drive speakers. In either case, you will require a power amp to provide the drive level needed for the 8 ohm speaker load.
