Hello,
On openSUSE Tumbleweed, recognizing the Marantz HD-AMP1 became
difficult starting with kernel 6.18.7, and the difficulty
significantly increased with kernel 6.18.9.
$ inxi -A
Audio:
Device-1: NVIDIA AD106M High Definition Audio driver: N/A
Device-2: Advanced Micro Devices [AMD/ATI] Radeon High Definition Audio
[Rembrandt/Strix] driver: N/A
Device-3: Advanced Micro Devices [AMD] Family 17h/19h/1ah HD Audio
driver: N/A
Device-4: Generic USB Audio driver: hid-generic,snd-usb-audio,usbhid
type: USB
Device-5: D&M Holdings (Denon/Marantz) HD-AMP1 driver: snd-usb-audio
type: USB
API: ALSA v: k6.18.9-1-default status: kernel-api
Server-1: PipeWire v: 1.5.85 status: active (process)
$ cat /proc/asound/cards
0 [HDAMP1 ]: USB-Audio - HD-AMP1
D&M Holdings Inc. HD-AMP1 at usb-0000:08:00.0-8, high
speed
1 [Audio ]: USB-Audio - USB Audio
Generic USB Audio at usb-0000:08:00.0-10, high speed
However, since it doesn't recognize the HD-AMP1, I keep repeating this
process;
$ sudo systemctl restart systemd-udev-trigger.service
