04:58 <massoud> narmstrong: thanks for your input, coming to my HDMI ARC question, do you know if X3 can do ARC on the HDMI interface ? X4 can do eARC from the bloc diagram but I am wondering for the others meson socs ?

05:09 <narmstrong> massoud: x3 maybe not, but the s905d3 yes

05:09 <debiangamer> There is no sound heard from the AV port of Sunvell T95Z Plus Amlogic S912. Using the 5.12.9-meson64 kernel with Armbian Debian Sid Xfce. There are no acodec related erros in logs. This command seems to work fine but no sound: aplay -D sysdefault:CARD=P230Q200 Ensoniq-ZR-76-01-Dope-77.wav. amixer shows Simple mixer control 'ACODEC',0 and other

05:09 <debiangamer> ACODEC devices.Pipewire is running and pavucontrol shows volume changes in output that is Built-in Audio Stereo but no sound can be heard.

05:55 <debiangamer> sysdefault:CARD=P230Q200 is the HDMI audio port and audio can be heard after plugging headphones to the monitor.

06:46 <debiangamer> There are these messages in dmesg when playing with pulseaudio applications and the only audio port available in pavucontrol: [ 3040.060547] hdmi-audio-codec hdmi-audio-codec.4.auto: Not able to map channels to speakers (-22)

06:46 <debiangamer> [ 3040.060637] hdmi-audio-codec hdmi-audio-codec.4.auto: ASoC: error at snd_soc_dai_hw_params on i2s-hifi: -22

06:46 <debiangamer> [ 3040.060664] gx-sound-card sound: ASoC: PRE_PMU: be.dai-link-4-playback event failed: -22

07:05 <debiangamer> Switching stereo output to multichannel and back in the pavucontrol Configuration tab makes pulseaudio apps to work.

18:30 <hyc> hey, so are the mainline S912 kernels 64bit, or 32bit only?

18:30 <hyc> seems like Amlogic only ever shipped 32bit support

18:31 <hyc> CoreElec says the amlogic 4.9 kernel is best supported

18:31 <hyc> neither coreelec nor libreelec mention ehether they're 32bit or 64bit

18:32 <hyc> damned annoying lack of details on their About pages

18:49 <debiangamer> hyc: the mainline S912 kernels 64bit only. Latest stable kernels has the best support, the version 5.12.9 currently.

19:00 <khilman> more specifically, the upstream kernels are 64-bit, but can support 32-bit userspace (c.f. CONFIG_COMPAT)

19:47 <hyc> cool, I'm only interested in 64bit userland

19:47 <hyc> thanks

19:49 <hyc> and do these also support android userspace?
