Hello. With an firmware not updated since «Last update May 9, 2011» I think it's safe to say that this card will never work at higher sample rate - running linux. It's not «legacy» on the Sound Devices web site, i wonder why. The list keep an old talk on this card and this problem : https://lists.linuxaudio.org/archives/linux-audio-user/2014-September/099206.html Older : https://lists.linuxaudio.org/archives/linux-audio-user/2013-January/089199.html And i can quote a support email from Sound Devices where i asked about this issues - wich is not an issue for them for sure.

I don't know when or if they will make this request available but I will gladly pass this request to engineering for future firmware consideration. Thanks. Best Regards, John Doe -- John Doe Tech Support Web: www.sounddevices.com So, more thant 4 years later, firmware still the same, problem not solve. Sad. Bravo sound devices !
