Apparently you are hitting t= he KASSERT in vchan_setnew(). It would be very helpful to see what KASSERT pri= nts (i.e what the values of newcnt and vcnt are). Can you also share your /boot/loader.conf, hw.snd and hw.usb.uaudio? --=20 You are receiving this mail because: You are the assignee for the bug.=
