Hello, contributors. @sjoerd-ccu @rkhuangtao @arndb @broonie @AxelLin
These days I've been testing spdif transmitting from rk3328, using firefly aio-rk3328-jd4 core board. I get stuck on playback of 88.2k/24bit, 96k/24bit, 176.4k/16bit(24bit) and 192k/16bit(24bit), as it sent nothing from spdifm1_tx pin.
I used dmesg to get the kernel log as follows:
[ 8252.009035] dma-pl330 ff1f0000.dmac: Reset Channel-4 CS-20400f FTC-1
[ 8267.250622] dma-pl330 ff1f0000.dmac: Reset Channel-4 CS-20400f FTC-2000
I used wav file with aplay command:
aplay -D plughw:2,0 192000-16.WAV
and got the feedback message:
Playing WAVE '192000-16.WAV' : Signed 16 bit Little Endian, Rate 192000 Hz, Stereo
^CAborted by signal Interrupt...
aplay: pcm_write:1939: write error: Input/output error
So what's the problem? Could somebody kindly test with the audio files as I mentioned above?
Sincerely,
Willard.
