I have a Lenovo Thinkstation P330, running Tumbleweed, it has both integrated sound and graphics and an NVIDIA Quadro P400 card. Previous to running Tumbleweed I ran Debian, Fedora and POP!_OS, all of these allowed me to pass audio through the display port of the NVIDIA card, to my screen. Under Tumbleweed this does not work however. It looks like the NDIVIA pass-through is not seen at all. cat /proc/asound/cards 0 [PCH ]: HDA-Intel - HDA Intel PCH HDA Intel PCH at 0xb4230000 irq 142 1 [C920 ]: USB-Audio - HD Pro Webcam C920 HD Pro Webcam C920 at usb-0000:00:14.0-7.2, high speed The following document in section 10.3 talks about the under emulation of logical devices, I'm wondering if this could be related to the issue as I don't see the NVIDIA sound device at all. https://download.nvidia.com/XFree86/gpu-hdmi-audio-document/#issues_in_alsa aplay -L null Discard all samples (playback) or generate zero samples (capture) speexrate Rate Converter Plugin Using Speex Resampler pipewire PipeWire Sound Server pulse PulseAudio Sound Server upmix Plugin for channel upmix (4,6,8) default Default ALSA Output (currently PulseAudio Sound Server) sysdefault:CARD=PCH HDA Intel PCH, ALC233 Analog Default Audio Device front:CARD=PCH,DEV=0 HDA Intel PCH, ALC233 Analog Front speakers surround21:CARD=PCH,DEV=0 HDA Intel PCH, ALC233 Analog 2.1 Surround output to Front and Subwoofer speakers surround40:CARD=PCH,DEV=0 HDA Intel PCH, ALC233 Analog 4.0 Surround output to Front and Rear speakers surround41:CARD=PCH,DEV=0 HDA Intel PCH, ALC233 Analog 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=PCH,DEV=0 HDA Intel PCH, ALC233 Analog 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=PCH,DEV=0 HDA Intel PCH, ALC233 Analog 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=PCH,DEV=0 HDA Intel PCH, ALC233 Analog 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers hdmi:CARD=PCH,DEV=0 HDA Intel PCH, HDMI 0 HDMI Audio Output hdmi:CARD=PCH,DEV=1 HDA Intel PCH, HDMI 1 HDMI Audio Output hdmi:CARD=PCH,DEV=2 HDA Intel PCH, HDMI 2 HDMI Audio Output hdmi:CARD=PCH,DEV=3 HDA Intel PCH, HDMI 3 HDMI Audio Output hdmi:CARD=PCH,DEV=4 HDA Intel PCH, HDMI 4 HDMI Audio Output -- You are receiving this mail because: You are on the CC list for the bug.
