My Wavelength Proton USB DAC works with the "default" device and with "plughw:0,0", but it does not work with "hw:0,0". I get the following error: output: Failed to open "Wavelength Proton" [alsa]: ALSA device "hw:0,0" does not support format 16: Invalid argument When trying to play a 24-bit file instead of 16-bit, "16:" is replaced by "24:" in the error message. The DAC supports 16-bit and 24-bit audio, and the manufacturer has assured me that it enumerates with Windows and Mac without error. Does this look like an ALSA bug? - Grant ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
