Digitalman1983 Posted November 18, 2020 Share Posted November 18, 2020 On the 20.08.2 Buster release (Kernel 5.8.6) the headphone jack is not currently working. HDMI audio seems to be supported. aplay -L returns only the HDMI audio interface. (sun50i-a64-hdmi) but is not showing the headphone interface (should additionally show sun50i-a64-audio as in other working builds) This is also the case with the current development build (Armbian_20.11.0-trunk.32_Lime-a64_buster_current_5.9.7) A look at the device tree shows “<stdout>: Warning (unit_address_vs_reg): Node /sound/simple-audio-card,dai-link@0 has a unit name, but no reg property” on the first line of the DTS of sun50i-a64-olinuxino, sun50i-a64-olinuxino-emmc, and sun50i-a64-olinuxino-2Ge8G device tree blobs. Not sure if this is a contributing factor. The snippet it seems to be complaining about: simple-audio-card,dai-link@0 { format = "i2s"; frame-master = <0x11>; bitclock-master = <0x11>; mclk-fs = <0x80>; I did some digging and found this patch from a few years ago: https://www.alsa-project.org/pipermail/alsa-devel/2018-October/141047.html The only major difference I see between the configuration added by the patch and my current device tree is that hex addresses are specified in place of pointer variables. (i.e. <0x12> vs <&dai> Going on the advice of several forum posts, I tried adding "overlays=analog-codec" to /boot/armbianEnv.txt to no avail. I suspect that analog audio needs to be enabled in kernel configuration. 0 Quote Link to comment Share on other sites More sharing options...
guidol Posted November 18, 2020 Share Posted November 18, 2020 seems to tbe a problem on devices with A64-CPU We got the "same" problem with Pine64 and the NanoPi A64 Maybe you could get a idea for a solution by checking the attached .dts for the NanoPi A64 in this message?: 0 Quote Link to comment Share on other sites More sharing options...
