Re: [SlimDevices: Touch] Async USB Dac Experiments - testers wanted...
Hi Triode, Did you find the way setting the chip to output 24/192 I2S to the built-in DAC? Happy to involve in testing if it is ready.

Triode, Any chance to look into 24/192 I2S output again?

Given that it can output 24/192 with coaxial output, the chip itself is capable in handling it. Just need to find the right setting. Read your post on suggested setting.

Re: [SlimDevices: Touch] Announce: Enhanced Digital Output app - USB Dac and 192k Digital Ouput
Have modified SBT and taken the I2S signal to the internal DAC and use it to connect external DAC. I tested version 0.5 which only support up to 24/96. Would this new version make it work for 24/192 sampling? mldb's Profile: http://forums.slimdevices.com/member.php?userid=56216 View this thread: http://forums.slimdevices.com/showthread.php?t=94512 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
