I am unable to get Hardware monitoring working with my EWS88D card, yet it works perfectly with my Delta 1010LT (they are in the same machine running FC1 CCRMA). I checked the bug list last night on Alsa. I could find nothing for EWS88D or "PCI - ice1712" category related to H/W monitoring. The Alsa soundcard matrix says the EWS88D supports "H/W mixing". Is this the same as H/W monitoring? At present my theories are: 1. Perhaps there are different variationson the envy24/ice1712 chip and the EWS88D uses one that lacks H/W monitoring. 2. Terratec implementation of the envy24/ice1712 is 'broken'. 3. There is bug in ice1712 driver with regards to the EWS88D Any assistence ya'll can provide is appreciated. Regards, Robb NOTE: While the Alsa sound card matrix for the EWS88D states that "[To] IEC-60958 TOSLINK Output" works for the EWS88D. I can confirm that [Aio] should be added to the notes section. I've got the EWS88D ADAT In and ADAT Out plugged into a Berhinger ADA8000 via Lightpipe. Recording and playback work brilliantly with the ADA8000 set as Master for wordclock purposes. In fact, I will add this to Alsa Mantis system. . . silly me. Below is detailed information from ALSA, JACK, and ENVY24CONTROL.
