Do you mean the card is physically broken? Do you get error messages when you try to use it? Have you used a program such as alsamixer to bring up the volume level, which defaults to all the way off? > Everything seems to work fine, What is "everything"? You just said the first card didn't work right, and the second card had no output. > except that alsa uses my broken card, the ES1371 for audio output. If I understand ALSA correctly, this is because it is the default device -hw:0. I think you would need to explicitly tell ALSA to use a different device. Have you read up on .asoundrc files? (I haven't (I know I ought to) - but I think it might be the answer). > If I set jack to Playback via the card with index 1 , so my ESS-Solo1 (snd-es1938): > # jackd -d alsa -d hw:0 -P hw:1 Why do you say "-d hw:0" if you want it to use hw:1? Try this: jackd -d alsa -d hw:1 Good luck :) |) |)enji
