            Bug ID: 238587
           Summary: [hdac] AMD hdac + Realtek codec: occasionally stops
                    working with interrupt mode and needs polling
           Product: Base System
           Version: CURRENT
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs at FreeBSD.org
          Reporter: greg at unrelenting.technology

(Ryzen 1st gen on an MSI X370 SLI PLUS)

hdac1: <AMD (0x1457) HDA Controller> mem 0xfcf00000-0xfcf07fff irq 43 at device
0.3 on pci14
hdacc1: <Realtek ALC892 HDA CODEC> at cad 0 on hdac1
hdaa1: <Realtek ALC892 Audio Function Group> at nid 1 on hdacc1
pcm6: <Realtek ALC892 (Rear Analog 7.1/2.0)> at nid 20,22,21,23 and 24,26 on
hdaa1
pcm7: <Realtek ALC892 (Front Analog)> at nid 27 and 25 on hdaa1

Occasionally (not very often, sometimes it's like, a week without this)

- the sound stops working (playback starts stuttering on the same sample and
the progress in the music/video player stops going forward)
- I don't think any messages are logged (I'll recheck next time it happens)
- sysctl dev.hdac.1.polling=1 fixes the problem and playback resumes fine
