I now have another sparc clone (DTKstation/Classic+) that has an AMD7930 and
also a DBRI SBUS card.
The dbri.o driver from 2.4.27 (kernel-image-2.4.27-1-sparc32) seems to work
with that SBUS card:
audio0 at 0xfd01c000 (irq 57) is DBRI(e)+CS4215(18)
and the amd7930.o driver also found the other soundchip:
amd7930 at fd01a000 irq 61
However, even as root, mpg123 only says:
audio: INVALID ARGUMENT
A cat on /dev/sndstat only gives an error message but supporting sndstat is
not mandatory, anyway.
I guess that all necessary modules are loaded?:
Module Size Used by Not tainted
dbri 16352 0 (unused)
sunlance 9896 1
crc32 3248 0 [sunlance]
amd7930 7788 0
audio 23816 2 [dbri amd7930]
sr_mod 16088 0 (unused)
cdrom 27996 0 [sr_mod]
ext3 85292 2 (autoclean)
jbd 45860 2 (autoclean) [ext3]
sd_mod 11868 6 (autoclean)
esp 29200 3 (autoclean)
scsi_mod 61228 3 (autoclean) [sr_mod sd_mod esp]
Is there a console program that will definitely work, maybe even for MP3
playback (I want to see if they are fast enough for that).
Or should I use alsa instead?
Thnx
