As promised, this is my change:

linux/sound/mips/au1x00.c, function "snd_au1000_ac97_new":

...
    /* Initialise Au1000's AC'97 Control Block */
    au1000->ac97_ioport->cntrl = AC97C_RS | AC97C_CE;
    udelay(10);
    au1000->ac97_ioport->cntrl = AC97C_CE;

    /* Original delay 10us */
    /* udelay(10); */

    /* New delay 200ms */
    mdelay(200);

    /* Initialise External CODEC -- cold reset */
    au1000->ac97_ioport->config = AC97C_RESET;
    udelay(10);
    au1000->ac97_ioport->config = 0x0;
    mdelay(5);
...
