If I go to Help – Audio > Device Info, Audacity says “No Devices Found.” Any ideas? All good information from the other posters on this thread! However, let me add a bit of additional nuance: If you are using the standard Paravel setup on CentOS 7, AudioScience cards automatically get setup to use a special “HPI” driver (different from the ALSA driver used for all other sound cards). This has two important effects: 1) It lets Rivendell use several “advanced features” on the AudioScience card that are not available via the standard ALSA driver. 2) It makes the AudioScience card invisible to applications that don’t know how to use this special HPI driver —effectively, invisible to everything except Rivendell. The way around this is indeed to use another, non-AudioScience card to interface with Audacity. In this specific case (Rivendell using an AudioScience card), you don’t need to worry about those cards conflicting with each other; they each inhabit separate “domains” as it were. N.B. - If *neither* card is an AudioScience one, then you do indeed need to be careful about configuring which one gets used where, as noted by al davis in his post.
