Thanks, that's a good idea.

I agree that this is worthwhile. I'll do this before reviewing the kernel code.

Before I could check dmesg of 3.12 I had a skirmish with systemd (I tried to change to upstart) so, long story short, I lost the kernel. I probably shouldn't have, but I didn't know how to fix the init system. Once Debian moves ahead with their kernel versions I'm not sure how to get the old packages. Regardless, I can't submit a bug against the kernel when I use a Debian kernel. I downloaded, configured, and compiled 3.10.51, 3.12.1, 3.12.26, and 3.16. They all exhibit the same issues: 44.1 kHz: static and silence 48 kHz: works well 88.2 kHz: static and silence 96 kHz: works well using either device: aplay -D iec958:DragonFly <file>.wav aplay -D plughw:DragonFly <file>.wav dmesg: usb 4-2: 1:1: cannot get freq at ep 0x1 ------------------------------------------------------------------------------ _______________________________________________ Alsa-user mailing list Alsa-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/alsa-user
