THX a lot. Plugged the card in a while ago to see that it is recognised and the module is there. card 0: TXRX [MXC SPDIF TX/RX], device 0: MXC_SPDIF [MXC_SPDIF] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: default [USB Audio DAC ], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: fab4 [fab4], device 0: fab4-ak4420 [] Subdevices: 0/1 Subdevice #0: subdevice #0 Somehow the Wolfson is thrown out on aplay -l and shown in /proc/asound/cards - a bit weired. And the jive_alsa process for "default" is not coming up (havn't changed the asound.conf yet). I'll check it out later. "jive_alsa default" sends out 24bit. Perhaps that'll be a problem on my PCM 2707-16bit. Did you figure out if there is a way to assign indexes ( as done on non embedded distros) to the cards? Would be nice to be able to assign the USB card to e.g. card 2 if 24bit would cause any problems. Anyhow. THX a lot for now. I gotta feeling that things get too complicated. Jumping from here to there. BTW: Did you see that the /proc/asound/version shows 1.0.16 and aplay --version is giving you 1.0.18 !?!? Hmmh.
