Hi all, I asked this question on the alsa-user list but haven't received a reply so I thought I would ask here. I have two ENS1371 based cards plugged into the one machine: root@sound:~# cat /proc/asound/cards 0 [AudioPCI ]: ENS1371 - Ensoniq AudioPCI Ensoniq AudioPCI ENS1371 at 0xa400, irq 10 1 [AudioPCI_1 ]: ENS1371 - Ensoniq AudioPCI Ensoniq AudioPCI ENS1371 at 0x9400, irq 5 I have also set up a /etc/asound.conf file containing aliases for the cards named "card0" and "card1". I have also run alsamixergui with "-c 0" and "-c 1" parameters to set up output volumes on the two cards (and the controls on the two alsamixergui instances behave independantly). However, when I playback a sound file using: aplay -D card0 a.wav aplay -D card1 a.wav Only card0 produces sound. I have also tried physically swapping the cards but only card0 produces sound. I have also tried the -v option to aplay to confirm that the output is going to device 0 and device 1. I'm out of ideas about this. Does anybody have any hints on how I might get this going?
