foscove Posted September 28, 2022 Share Posted September 28, 2022 Long story short: I used for about one year an odroid HC4 as NFS server and worked fine. Now I would add a player service for it. It mounts an HDMI port, so I tried to plug in the cable and it worked. I were able to see the video output but with no sound. I found there is no detected hdmi card: # aplay -l **** List of PLAYBACK Hardware Devices **** card 0: ODROIDHC4 [ODROID-HC4], device 0: fe.dai-link-0 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: ODROIDHC4 [ODROID-HC4], device 1: fe.dai-link-1 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: ODROIDHC4 [ODROID-HC4], device 2: fe.dai-link-2 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 tried again after # alsactl init alsa-lib main.c:1541:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -2 Found hardware: "axg-sound-card" "" "" "" "" Hardware is initialized using a generic method (alsactl -U init provides no error) The modules side looks fine to me (it was the same on 5.10.144, I tried moving to 5.19.10 with no result): # lsmod | grep snd snd_soc_hdmi_codec 24576 1 snd_soc_meson_axg_sound_card 16384 0 snd_soc_meson_card_utils 16384 1 snd_soc_meson_axg_sound_card snd_soc_meson_g12a_tohdmitx 20480 1 snd_soc_meson_codec_glue 16384 1 snd_soc_meson_g12a_tohdmitx snd_soc_meson_axg_tdmout 24576 1 snd_soc_meson_axg_frddr 36864 3 snd_soc_meson_axg_fifo 20480 1 snd_soc_meson_axg_frddr snd_soc_meson_axg_tdm_interface 16384 2 snd_soc_meson_axg_sound_card snd_soc_meson_axg_tdm_formatter 16384 2 snd_soc_meson_axg_tdm_interface,snd_soc_meson_axg_tdmout snd_soc_core 245760 10 snd_soc_meson_axg_tdm_formatter,snd_soc_meson_axg_sound_card,snd_soc_hdmi_codec,snd_soc_meson_g12a_tohdmitx,snd_soc_meson_axg_tdm_interface,snd_soc_meson_axg_fifo,snd_soc_meson_axg_tdmout,snd_soc_meson_axg_frddr,snd_soc_meson_card_utils,snd_soc_meson_codec_glue snd_compress 24576 1 snd_soc_core ac97_bus 16384 1 snd_soc_core snd_pcm_dmaengine 20480 1 snd_soc_core snd_pcm 131072 7 snd_soc_hdmi_codec,snd_compress,snd_soc_meson_axg_tdm_interface,snd_soc_core,snd_soc_meson_axg_fifo,snd_soc_meson_codec_glue,snd_pcm_dmaengine snd_timer 40960 1 snd_pcm snd 90112 5 snd_soc_hdmi_codec,snd_timer,snd_compress,snd_soc_core,snd_pcm soundcore 16384 1 snd I tried digging in dmesg and the only related issue that came out is:p panfrost ffe40000.gpu: error -ENODEV: dev_pm_opp_set_regulators: no regulator (mali) found but I wouldn't say that to be the source of the sound problem. There are errors but I don't feel the solution behind any of them. Do you? Kernel, modules, drive, dtb... where else could the lack of sound come from? Any suggestion? 0 Quote Link to comment Share on other sites More sharing options...
