Yup, I think it's got something to do with this code in
if (ei->index == EAP_DAC2)
sic |= EAP_SET_P2_ST_INC(0)
| EAP_SET_P2_END_INC(param->precision * param->factor / 8);
.. or so I'd remember that removing it would make audio0 gurgle instantly.
With it, audio starts gargling after playing a little while.
Anyways, by using the second (first, actually ;) dac the problem doesn't
exist at all.
