Hi Stefan, thank you for your response. > i assume you set this option in the config.txt? This shouldn't have any > affect for the mainline kernel / DT. I am aware of that... I did "snd_bcm2835 enable_hdmi=0" in /etc/modules. "modinfo snd_bcm2835" shows as below. Doesn't it indicate snd_bcm2835 having an option enable_hdmi??? It seems that the contention of grabbing HDMI audio output between vc4.ko and snd_bcm2835.ko can be addressed if snd_bcm2835.ko honors the option enable_hdmi with its default =0, but currently enable_hdmi seems having no effect in behavior of snd_bcm2835... # modinfo snd_bcm2835 filename: /lib/modules/5.10.0-5-rt-arm64/kernel/drivers/staging/vc04_services/bcm2835-audio/snd-bcm2835.ko alias: platform:bcm2835_audio license: GPL description: Alsa driver for BCM2835 chip author: Dom Cobley depends: snd-pcm,vchiq,snd staging: Y intree: Y name: snd_bcm2835 vermagic: 5.10.0-5-rt-arm64 SMP preempt_rt mod_unload modversions aarch64 sig_id: PKCS#7 signer: Debian Secure Boot CA sig_key: 4B:6E:F5:AB:CA:66:98:25:17:8E:05:2C:84:66:7C:CB:C0:53:1F:8C sig_hashalgo: sha256 signature: omitted, too long. parm: force_bulk:Force use of vchiq bulk for audio (bool) parm: enable_hdmi:Enables HDMI virtual audio device (bool) parm: enable_headphones:Enables Headphones virtual audio device (bool) parm: enable_compat_alsa:Enables ALSA compatibility virtual audio device (bool) parm: num_channels:Number of audio channels (default: 8) (int) Best regards, Ryutaroh
