Driver via ac97 sound problem (VT82C686) Compaq Presario 700
A message that is not in the archive (sent off-list or not yet received): [email protected]
Hi:
All the problems i tell you occurs when i try to access to register invia_card_init_proc. If i try to do this in 1886 initialization ( ac97_codec.c ) i haven't got any problem, i can write the registers of the 1886 and i can read then perfectly.
But my question is, later i set up 1886 chip, does via inicialization
change my configuration of it? If i try to print all the register of the 1886 in via_card_init_proc it fails :( and i can't be sure that via code doesn't change them.
my 1886_setup proc is now as this:
static int setup_ad1886(struct ac97_codec * codec)
{
int cnt;
/* The spec says not to mess with other bits unless S/PDIF is turned *off* in reg 2A */ //codec->codec_write(codec, AC97_EXTENDED_STATUS, 0);
/* The 1886 spec dated 08/25/00 says default value=0
but ac97 2.2 says it should be 0x2000. */
// codec->codec_write(codec, AC97_RESERVED_3A, 0x0000); /* 48 kHz */ codec->codec_write(codec, 0x0002, 0x003f); codec->codec_write(codec, 0x0004, 0x003f); codec->codec_write(codec, 0x0006, 0x003f); codec->codec_write(codec, 0x000a, 0x003f); codec->codec_write(codec, 0x000c, 0x003f); codec->codec_write(codec, 0x000e, 0x003f); codec->codec_write(codec, 0x0010, 0x0808); codec->codec_write(codec, 0x0012, 0x083f); codec->codec_write(codec, 0x0014, 0x0808); codec->codec_write(codec, 0x0016, 0x0808); codec->codec_write(codec, 0x0016, 0x0808); codec->codec_write(codec, 0x0018, 0x0808); codec->codec_write(codec, 0x001a, 0x0000); codec->codec_write(codec, 0x001c, 0x0800); codec->codec_write(codec, 0x0020, 0x0000); codec->codec_write(codec, 0x0022, 0x000f); codec->codec_write(codec, 0x0028, 0x0005); codec->codec_write(codec, 0x002c, 0xbb80); codec->codec_write(codec, 0x007a, 0xbb80); codec->codec_write(codec, 0x0032, 0xbb80); codec->codec_write(codec, 0x0078, 0xbb80); codec->codec_write(codec, 0x003a, 0x0000); codec->codec_write(codec, 0x0072, 0x0000); codec->codec_write(codec, AC97_EXTENDED_STATUS, 1); codec->codec_write(codec, AC97_RESERVED_3A, 0x2000); /* 48 kHz */
for (cnt=0; cnt <= 0x7e; cnt = cnt +2)
printk(KERN_INFO "reg:0x%02x val:0x%04x\n", cnt,codec->codec_read(codec, cnt));
return 0;
}
and the output in /var/log/messages is:

As you can see, the register are well written in ad1886, so this are my question,
---- Does via code inicialization change any value of ad1886? ---- Is possible that ad1886 works fine and the problem were with via chipset?
----- Any suggestion is welcomed.
Thanks
