Summary:                    No sound from speakers
Description: 
Alsa seems to detect the sound card, but when I try to actually play
something there is no sound from the speakers.

The Ensoniq chip says, assuming I'm looking at the right chip:

CREATIVE
ES1373
1373-0001-04
S     JC226A
0006H    Kor

I've never gotten the TV card sound working, really (in terms of physical
wiring and such).  So I have no idea whether I get sound from that...

It seem that snd_es1371_codec_read() cannot read the correct value.

The first thing is to find out the read/write of codec registers by
ens1371 by adding printk statement.



 static void snd_es1371_codec_write(struct snd_ac97 *ac97,
				   unsigned short reg, unsigned short val)
 {
	 struct ensoniq *ensoniq = ac97->private_data;
 	 unsigned int t, x;
+        printk(KERN_INFO "codec write %.2x = %.4x\n",reg,val);
	 mutex_lock(&ensoniq->src_mutex);
	 for (t = 0; t < POLL_COUNT; t++) {




			for (t = 0; t < POLL_COUNT; t++) {
				if ((x = inl(ES_REG(ensoniq, 1371_CODEC))) & ES_1371_CODEC_RDY) {
					mutex_unlock(&ensoniq->src_mutex);
+					printk(KERN_INFO "codec read %.2x : %x\n",reg, x);
					return ES_1371_CODEC_READ(x);
				}
			}
