I am trying to get software control of 8 channels of audio over
HDMI. I don't know very much about linux audio software and
naively assumed I'd plug an HDMI into an audio converter/splitter
and get 8 working outputs. What I get is silence. Someone here
must understand this and I'd appreciate help! Here's everything I know about collecting. Sorry for the length or if it's insufficient.
Code:
wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh && chmod +x ./alsa-info.sh && ./alsa-info.sh http://alsa-project.org/db/?f=9a8a1a...a1d071064900d5 Code:
uname -r 4.15.0-64-generic #I'm guessing this is what should work, but doesn't: speaker-test -D surround71:CARD=PCH,DEV=0 -c 8 Code:
speaker-test 1.1.3 Playback device is surround71:CARD=PCH,DEV=0 Stream parameters are 48000Hz, S16_LE, 8 channels Using 16 octaves of pink noise Channels count (8) not available for playbacks: Invalid argument Setting of hwparams failed: Invalid argument But trying speaker-test -D surround71:CARD=PCH,DEV=0 -c 2 doesn't return errors, but gives silence (even with the SKSL converter set to stereo) pavucontrol Unable to init server: Could not connect: Connection refused (But do I need it?) alsamixer shows Auto-Mute Disabled, Loopback Enabled. Master, Headphones, Speaker and PCM all have columns in the white (but a green 00 at the bottom). There's no line, front, center, side, rear, etc. There are 5 S/PDIF columns, all blank and showing 00, and I can't get them to change (but presumably I don't care.) inxi -Fxz System: Host: lachesis Kernel: 4.15.0-64-generic x86_64 bits: 64 compiler: gcc v: 7.4.0 Console: tty 0 Distro: Linux Mint 19.1 Tessa base: Ubuntu 18.04 bionic Machine: Type: Desktop System: Azulle product: Inspire v: N/A serial: <filter> Mobo: INTEL model: SKYBAY serial: <filter> UEFI: American Megatrends v: 5.12 date: 10/10/2017 CPU: Topology: Dual Core model: Intel Core i5-7200U bits: 64 type: MT MCP arch: Kaby Lake rev: 9 L2 cache: 3072 KiB flags: lm nx pae sse sse2 sse3 sse4_1 sse4_2 ssse3 vmx bogomips: 21696 Speed: 619 MHz min/max: 400/3100 MHz Core speeds (MHz): 1: 600 2: 600 3: 601 4: 600 Graphics: Device-1: Intel HD Graphics 620 driver: i915 v: kernel bus ID: 00:02.0 Display: server: X.org 1.19.6 driver: modesetting unloaded: fbdev,vesa tty: 154x34 Message: Advanced graphics data unavailable in console.
