I have searched through at91-ssc.c and I cannot figure out why the record
makes the pcm behave as it does. I am using PCM A, which configures the SSC
as:
case SND_SOC_DAIFMT_DSP_A | SND_SOC_DAIFMT_CBS_CFS:
/*
* DSP/PCM Mode A format, SSC provides BCLK and LRC clocks.
*
* The SSC transmit and receive clocks are generated from the
* MCK divider, and the BCLK signal is output on the SSC TK line.
*/
rcmr = (( ssc_p->rcmr_period << 24) & AT91_SSC_PERIOD)
| (( 1 << 16) & AT91_SSC_STTDLY)
| (( AT91_SSC_START_RISING_RF ) & AT91_SSC_START)

Which, while it puts my timing a little off, should allow a valid record if
one has TF0 and RF0 connected and TK0 and RK0 connected. Has anyone seen
this behavior before?
Looking at strace of arecord gives me a few lines I wonder about. I will
attach the entire strace dump as a text file. The lines that give me pause
are:
~ $ strace arecord -r8000 -traw -fS8 -d3 test.raw
execve("/usr/bin/arecord", ["arecord", "-r8000", "-traw", "-fS8", "-d3", "
test.raw"], [/* 7 vars */0

.snip.
The final sequence here. Seems that when it tried some kind of ioctl on
pcmC0D0c, it received an error. Perhaps this control signal is what is
causing the HW problems with RF0.
Again, the full strace is attached. Not sure if this helps, I am trying my
best to figure out what is wrong with RF0. I know it works as my polling ssc
driver works just fine with both capture and playback.
If anyone has any clue to what I can try, look at, etc. please feel free to
let me know.
