I think that regardless of how good the on-board DAC is, and that a 192k SPDIF out is available, we must have a fully working UAC2 implementation. And by that, I don't mean smoke and mirrors..... RT "hides" any issues up to 192k, but try and run any higher out of the USB port and it all falls apart with pops,clicks and dropouts galore.
Regarding the alsa debug settings that I asked if you could use, it must mean that the kernel you are using is not compiled with CONFIG_SND_PCM_XRUN_DEBUG and CONFIG_SND_DEBUG. I'm not familiar with the Angstrom distribution. I'll take a look at a couple of other distribution options (Arch / Ubuntu) and see if they enable the reqd options in their default kernel. I figure that loading an image onto a card is probably going to cause you less hair loss and wasted time than compiling kernels. I have tried to contact the person on diyaudio who told me to stay away from the Bone when I asked for experiences with UAC2 on Arm devices. No response as yet. I do know that he spent weeks trying to get perfect output with a WaveIO (XMOS), did try running a RT kernel, and while I don't know him personally from what he said it was pretty obvious that he was clued-up, rather than blindly tweaking settings. I'm going to order a 'Bone myself. If the USB is a lame duck, then I figure I can hack the davinci driver to output I2S to a reclocker, mount the Bone in the same box as the DAC and dump the USB->I2S convertor. The only problem is that Farnell in the UK are out of stock, so I will have to order from Mouser and wait 4 days for delivery. But maybe I'll get it before the weekend. ------------------------------------------------------------------------ JackOfAll's Profile: http://forums.slimdevices.com/member.php?userid=3069 View this thread: http://forums.slimdevices.com/showthread.php?t=97881 _______________________________________________ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss
