Tried sending you a message @ginf, but haven't heard back from you so I'm posting here instead; What kind of debug trace do you want me to give you logs from? $ /opt/qemu4/bin/qemu-system-x86_64 -d help Log items (comma separated): out_asm show generated host assembly code for each compiled TB in_asm show target assembly code for each compiled TB op show micro ops for each compiled TB op_opt show micro ops after optimization op_ind show micro ops before indirect lowering int show interrupts/exceptions in short format exec show trace before each executed TB (lots of logs) cpu show CPU registers before entering a TB (lots of logs) fpu include FPU registers in the 'cpu' logging mmu log MMU-related activities pcall x86 only: show protected mode far calls/returns/exceptions cpu_reset show CPU state before CPU resets unimp log unimplemented functionality guest_errors log when the guest OS does something invalid (eg accessing a non-existent register) page dump pages at beginning of user mode emulation nochain do not chain compiled TBs so that "exec" and "cpu" show complete traces trace:PATTERN enable trace events

The driver says the device is working correctly, but it does not. When I try to open the Windows sound configuration, the dialog hangs and never shows it's content. Several people reported this back in May: https://windowsreport.com/windows-10-v1903-ich6-ich9-virtio/ I can confirm I have exactly the same problem. Host is Arch Linux, current (5.2.5) kernel, QEMU 4.0. I enabled HDA debug output and compared an older, working Windows version to 1903, but could not see the difference. The driver seems to issue the same verbs. I am happy to provide additional information if needed.
