I have an Intel motherboard sound card, and twoHDMI audio sound cards provided by each of my ATI video cards: # lspci | grep -i audio 00:1b.0 Audio device: Intel Corporation Patsburg High Definition Audio Controller (rev 05) 01:00.1 Audio device: ATI Technologies Inc Device aaa0 02:00.1 Audio device: ATI Technologies Inc Device aaa0 I don't have anything plugged into the ATI HDMI ports so I want to disable those devices, as I get annoying error messages in KDE at startup time and periodically in /var/log/messages. For example: [ 13.018758] ALSA sound/pci/hda/hda_eld.c:334 HDMI: ELD buf size is 0, force 128 [ 13.018772] ALSA sound/pci/hda/hda_eld.c:351 HDMI: invalid ELD data byte 0 I cannot blacklist the module, because the "snd_hda_intel" module that drives the Intel sound card on my motherboardalso recognizes the ATI cards, according to lspci-v. The following solution does workperfectly: # echo 1 > /sys/devices/pci0000:00/0000:00:02.0/0000:01:00.1/remove # echo 1 > /sys/devices/pci0000:00/0000:00:03.0/0000:02:00.1/remove In the old days, the above two lines would go into rc.local. What is the systemd way to not create those devices? Or is there an alternate approach to turn off the HDMI sound cards on the ATI cards?
