Added a few debug statement in the driver to be able to see what is going on.
Things to notice are
1. The drive sets I2S (correct)
2. Bit size 16 bit (correct) and sample rate is correct 44.1K
3. the CODEC is powered up be a PREPARE and then a ON
4. The requested clock is 12MHZ, but something reports it's changed to 12.5MHZ ? Would this case an issue ?
5. The Input/Output error how up after a few seconds of starting the playback.
6. The commands to play is:
amixer -c 0 cset iface=MIXER,name='ASI_RX_CH1_EN Switch' on amixer -c 0 cset iface=MIXER,name='OUT1x Source' 'DAC Input’ amixer -c 0 cset iface=MIXER,name='OUT1x Config' 'Differential’ amixer -c 0 cset iface=MIXER,name='OUT1x Driver' 'Line-out’ amixer -c 0 cset iface=MIXER,name='ASI_RX_CH2_EN Switch' on amixer -c 0 cset iface=MIXER,name=‘OUT2x Source' 'DAC Input’ amixer -c 0 cset iface=MIXER,name=‘OUT2x Config' 'Differential’ amixer -c 0 cset iface=MIXER,name=‘OUT2x Driver' 'Line-out' aplay -c 2 -f S16_LE -r 44100 -d 15 --device='hw:0,0' pure_tone_44.1K_16b_stereo.wav
7. The I2S clock is 200000000 ? (200 MHz? )
The following shows up always after 6 seconds, after starting the aplay file (could be because loading the file?)
Red is from aplay, blue and purple added debug output statement in the tac5x1x driver
aplay: pcm_write[ 375.714443] tac5x1x_set_sysclk 0 0 0
:2058: write err[ 375.719156] tac5x1x-codec 2-0051: recover cclk from bclk
or: Input/output error
