Hi all! I updated from DSM 6 to 7 on my HPE Microserver Gen8 (baremetal install, emulating DS3622xs+, current DSM 7.1-42661 Update 1) and on 2nd try all went well but now I cannot access my USD DAC E30, which earlier DSM "saw" as USB Speakers, and new DSM "sees" (i.e. if I connect it, writes "USB audio in info) but I cannot use it with Audio Station. I've searched both this forum and the net for a solution, and found at least two variants to install USB drivers to DSM7 the first is here, https://mariushosting.com/synology-how-to-add-usb-support-on-dsm-7/ and the idea is a short script that uses modprobe and lter another using insmod. I tried it as described and by accessing via SSH. I successfully added (at least no errors were shown) drivers, but it still does not "see" DAC as a possible output for Audio station the second option is a bit harder, so I haven't tried it yet, it can be found here https://github.com/robertklep/dsm7-usb-serial-drivers - here the problem is that in the list of Supported platforms there is no broadwellnk - I guess it can be the same as one of the lisyed but I cannot be sure I will be glad if this info helps anyone and still hope that someone will tell me a step-by-step way to recover my access to USB DAC, preferably w/o rebuilding the whole system (my meagre skills mean I may err even in simplest tasks) I guess I have to find out what USB driver is used by my DAC (how?) and then to get it from linux which runs the same core as my NAS (again how?) If there are any guides on this forum, which I missed, please direct me
