    I have same issue on vanilla 4.19 kernel and OrangePi Lite board. I think it is related to rtl8189fs driver. @ap17 Can you share solution for this issue?

    Hi, I have similar problem. I am trying to run simple PCM5102 based DAC over I2S on BananaPro board but I got errors when I am try to play something. I have added to dts file: pcm5102a: pcm5102a { #sound-dai-cells = <0>; compatible = "ti,pcm5102a"; status = "okay"; }; sound { compatible = "simple-audio-card"; simple-audio-card,format = "i2s"; simple-audio-card,cpu { sound-dai = <&i2s0>; }; simple-audio-card,codec { sound-dai = <&pcm5102a>; }; }; and &i2s0 { pinctrl-names = "default"; pinctrl-0 = <&i2s0_pins_a>; status = "okay"; }; After replacing dtb file and rebooting card is visible: # aplay -L null Discard all samples (playback) or generate zero samples (capture) default:CARD=sun4icodec sun4i-codec, Default Audio Device sysdefault:CARD=sun4icodec sun4i-codec, Default Audio Device default:CARD=D1c22400i2spcm5 1c22400.i2s-pcm5102a-hifi, Default Audio Device sysdefault:CARD=D1c22400i2spcm5 1c22400.i2s-pcm5102a-hifi, Default Audio Device but when I'm trying to play something I got error messages. Below I put output from aplay and speaker-test commands. # aplay -c 2 -D hw:1,0 /usr/share/sounds/alsa/Front_Center.wav Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono aplay: set_params:1305: Channels count non available # speaker-test -t wav -c 2 -D hw:1 speaker-test 1.1.3 Playback device is hw:1 Stream parameters are 48000Hz, S16_LE, 2 channels WAV file(s) Rate set to 48000Hz (requested 48000Hz) Buffer size range from 128 to 131072 Period size range from 64 to 16384 Using max buffer size 131072 Periods = 4 Unable to set hw params for playback: Invalid argument Setting of hwparams failed: Invalid argument After speaker-test I got following kernel message: sun4i-i2s 1c22400.i2s: ASoC: can't set 1c22400.i2s hw params: -22 Anybody knows what is wrong with my configuration?
