I didn't get that far yet :-(
Aparently it should work, but doesn't with my board revision
Mine is model no. CT4751

Updated symptoms: Sometimes plays, (usually twice) and then the interrupts
stop coming. I assume something is not being reset that my board revision
is sensitive to.

With debugging compiled in, a successful play looks like

eap: eap_halt_output
eap: eap_halt_input
eap: eap_halt_output
eap: eap_halt_input
eap_trigger_output: sc=0xc0494a00 start=0xc5399000 end=0xc53a7fc0 blksize=4384 i
ntr=0xc012f880(0xc048f800)
eap_trigger_output: DAC2_ADDR=0x21000, DAC2_SIZE=0x3bef
eap_trigger_output: set ICSC = 0x00000000
eap_intr: ICSS=0xa0080ec2, SIC=0xff900608
eap_intr: ICSS=0xa0080ec2, SIC=0xff900608
...

And an unsuccessful play looks like

eap: eap_halt_output
eap: eap_halt_output
eap: eap_halt_input
eap: eap_halt_output
eap: eap_halt_input
eap: eap_halt_output
eap: eap_halt_input
eap_trigger_output: sc=0xc0494a00 start=0xc5399000 end=0xc53a7fc0 blksize=4384 i
ntr=0xc012f880(0xc048f800)
eap_trigger_output: DAC2_ADDR=0x21000, DAC2_SIZE=0x3bef
eap_trigger_output: set ICSC = 0x00000000

<at this point I press ctrl-C & wait lots>

audio_sleep: woke up st=35
eap: eap_halt_output
eap: eap_halt_output
eap: eap_halt_input

Does this mean anything to anybody, I'm a complete beginner at kernel
hacking?

Thanks,
James
