Thanks to some recent help here, I've now found several applications that appear to control my DIO2448 with ALSA. I still can't get it to record fromt he SPDIF input though. ALSA has installed the generic CMI PCI 8738 driver, which I believe is the correct thing to do. Apps like alsamixergui have the right switches, but something seems to be disabled. The IEC958 In select doen't respond, and I can't find any docs which explain, e.g. - what combination of controls is required for this - what "IEC958 IN Valid" means (it's a control input, not a status display...) - what values I'm likely to need to change with iecset I can enable/disable monitoring of IEC958 input though analog output, and the IEC958 phase invert has the expected effect, so the driver is installed correctly. Should I be able to record with Audacity 1.2.0, with the alsa-oss package installed? Audacity plays OK. -- Anahata anahata@xxxxxxxxxxxxxx -+- http://www.treewind.co.uk Home: 01638 720444 Mob: 07976 263827
