DomiJi Posted June 25, 2018 Share Posted June 25, 2018 Hello Allo Team, i've got a USBridge with DietPi Allo Gui and use it with my iDSD micro. I sold the iDSD today and ordered a Mytek192 DSD. Did the USBridge support the relatively old Mytek192 DSD with the installed DietPi Allo Gui? Thanks and many greetings Dominik Link to comment
Methroix Posted October 31, 2018 Share Posted October 31, 2018 I just received my Allo USBridge and discovered that it indeed does not play at all with my Mytek 192 DSD. Some rather late research suggests that USB2 on the Mytek is a no-go since it requires drivers, which does not exist for Linux. Using USB1.1 my Mytek is discovered correctly, but only static noise is played. Perhaps @allo.com can shed further light on this? I'm now debating whether to return the unit or not, since my next planned upgrade is a Schiit DAC, which I sincerely hope will work. Link to comment

Roon ? ... can you do ssh login and share below commands results lsusb lsusb -t cat /proc/asound/card1/stream0 Allo.com Tech. Support Link to comment

Yes, USB 1.1 has now been working quite well. However, the intermittent 'pops' that appear about once a minute are a bit bothersome. Is this something I should discuss with Mytek as well? I've not tried USB 1.1 on the Mytek together with my PC, but with USB 2 there have never been any misbehavior. Link to comment
