Although au8830 may support mulitple codecs and there is a unconnected
20-pins connectors on my au8830 (Subsystem 12eb:0088)

There is only one STAC9708 (4-channels) audio codec on my au8830

It look like a control register rather than a status register.

Vortex: init.... <6>CODEC_EN : 00000000
CODEC_EN : 00000300
CODEC_EN : 00003300
CODEC_EN : 00003f00
done.


	/* Enable codec channels 0 and 1. */
	printk(KERN_INFO "CODEC_EN : %.8x\n",hwread(vortex->mmio,
VORTEX_CODEC_EN));
	hwwrite(vortex->mmio, VORTEX_CODEC_EN,
		hwread(vortex->mmio, VORTEX_CODEC_EN) | EN_AUDIO0 );
	printk(KERN_INFO "CODEC_EN : %.8x\n",hwread(vortex->mmio,
VORTEX_CODEC_EN));
#ifndef CHIP_AU8820
	hwwrite(vortex->mmio, VORTEX_CODEC_EN,
		hwread(vortex->mmio, VORTEX_CODEC_EN) | EN_AUDIO1 );
	printk(KERN_INFO "CODEC_EN : %.8x\n",hwread(vortex->mmio,
VORTEX_CODEC_EN));
	hwwrite(vortex->mmio, VORTEX_CODEC_EN,

	printk(KERN_INFO "CODEC_EN : %.8x\n",hwread(vortex->mmio,
VORTEX_CODEC_EN));
