No, AFAIK. There can be rather complex relations between those variables and also between other hw-specific things that make compiling a list of supported values quite difficult. For example playback (capture is different) on some echoaudio cards can use U8 and S32_BE with 1 channel only, S16_LE with 2 channels and S24_3LE and S32_LE with 1, 2, 4, 6, 8... channels. Sample rate is 32-96KHz but it's limited to 48KHz in ADAT mode even if you are using an analog output. Number of digital channels is 8 in ADAT mode and 2 in S/PDIF mode. Those constraints are enforced with ad-hoc functions in the card driver. Maybe (I know very little of the userspace API) you can get an "overall" feature list like "96KHZ, 8channels, S16_LE...", but the actual capabilities are know to the driver only. -- Giuliano. ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
