Audio on Sunblade 100

[Christian Ramseyer]

Hi

I'm trying to get sound on a Sunblade 100 with 7.2R. I've added

device          sound
device          snd_t4dwave

to the kernel and recompiled. pciconf shows an attached driver:

pcm0 at pci0:0:8:0:        class=0x040100 card=0x545110b9 chip=0x545110b9
rev=0x01 hdr=0x00
    vendor     = 'Acer Labs Incorporated (ALi/ULi)'
    device     = 'ALI M5451 PCI AC-Link Controller Audio Device'
    class      = multimedia
    subclass   = audio

However, there are errors in dmesg:

pcm0: <Acer Labs M5451> port 0x900-0x9ff mem 0x424000-0x424fff at device
8.0 on pci0
pcm0: <Analog Devices AD1881A AC97 Codec>
pcm0: [GIANT-LOCKED]
pcm0: [ITHREAD]
pcm0: chn_init(pcm0:record:dsp0.r0) failed: err = 19
pcm0: pcm_chn_create(trrchan, -1, 0xfffff80001370800) failed
pcm0: chn_init(pcm0:play:dsp0.p0) failed: err = 19
pcm0: pcm_chn_create(trpchan, 1, 0xfffff80001370800) failed

I've also found this message from 2006:
http://lists.freebsd.org/mailman/htdig/freebsd-sparc64/2006-June/004168.html

So, am I just doing something wrong or are there problems with 5451
audio on SPARC? I see that the release notes only list i386 and amd64 as
 architectures for the t4dwave driver.

By the way, thanks a lot for all the work your guys are doing in general
and for the SPARC port in particular. I'm currently trying BSD for the
first time in my life and I like it a lot. It runs surprisingly well on
this outdated platform.
