Hello

I am running -current and the audio device doesnt works properly.
The motherboard is VIA P4MA PRO.
The manual says:
-----------------
Chipset
* VIA P4M266/VT8235 chipset
  - Supports Intel Pentium4 and Celeron with 400 MHz (100MHz QDR) CPU
  - Front side bus
  - Integrated ProSavage8 AGP Graphics (KDE 3.1.2 works fine)
  - External 4X AGP Bus
  - High Bandwidth V-Link Client Controller
  - Integrated Hardware Sound Blaster/Direct Sound 6 channel AC'97 audio
  - Ultra DMA 66/100/133 master mode PCI EIDE Controller
  - ACPI 1.0B and APM 1.2 Compilant
[...]
Onboard Audio
* VIA VT1616 6 channel AC'97 Codec
------------------
My box is P4-2.4 GHz, 512 MB RAM, EIDE 40 GB.
And a part of dmesg is here

NetBSD almeria 1.6T NetBSD 1.6T (GENERIC) #0: Fri Jun 13 18:55:05 CDT 2003  gallegos@almeria:/usr/src/sys/arch/i386/compile/GENERIC i386

auvia0: codec invalid (this message is when I startkde)
A lot of these messages.


When I start KDE, I can hear the sounds (only when it starts), but no more sounds after.
sometimes appears a artsd.core in my homedir and sometimes my box
seems very slow... In this case, I can see artsd is eating lots of CPU (I use top to see it)

The file /usr/src/sys/dev/ic/ac97.c says the following:
        /*
         * IC Ensemble (VIA)
         *      http://www.viatech.com/en/datasheet/DS1616.pdf
         */
        { AC97_CODEC_ID('I', 'C', 'E', 0x01),
          0xffffffff,                   "ICEnsemble ICE1230/VT1611",    },
        { AC97_CODEC_ID('I', 'C', 'E', 0x11),
          0xffffffff,                   "ICEnsemble ICE1232/VT1611A",   },
        { AC97_CODEC_ID('I', 'C', 'E', 0x14),
          0xffffffff,                   "ICEnsemble ICE1232A",  },
        { AC97_CODEC_ID('I', 'C', 'E', 0x51),
          0xffffffff,                   "VIA Technologies VT1616", ac97_vt1616_init },
        { AC97_CODEC_ID('I', 'C', 'E', 0),
          AC97_VENDOR_ID_MASK,          "ICEnsemble unknown",   },

Looking for a solution, I changed 0x51 to 0x52 to match with 0x49434552 of the last dmesg.
(Please note I dont know what am I doing here) and recompiled my kernel

The dmesg of these new kernel is here:

auvia0 at pci0 dev 17 function 5: VIA VT8235 AC'97 Audio (rev 0x50)
auvia0: interrupting at irq 5
auvia0: VIA Technologies VT1616 codec; headphone, 18 bit DAC, 18 bit ADC, KS Waves 3D
auvia0: variable rate audio, S/PDIF, center DAC, surround DAC, LFE DAC
audio0 at auvia0: full duplex, mmap, independent

[...]
auvia0: codec invalid (same result when I startkde)
Again, a lot of these messages.

I couldnt see difference with these kernel.

What can I do?

Thanks in advance
