Hi,
I've recently purchased an Epiphany Acoustic O2 sound card, basically
it's an USB DAC with a headphone amp. Problem is, the sound is barely
audible. I've tested the amp independently (using the line in) and it
works fine. So now I am trying to set up a preamp in alsa, but somehow
I can't get it working. The config is below. I'd be grateful for any
hints or ideas. Thanks,
