With Alsa loaded, playing a 44.1 KHz mp3. IEC settings in Alsamixer:
IEC958 5V enabled
IEC958 Copyright muted
IEC958 DAC To Out enabled
IEC958 In Monitor muted
IEC958 In Phase Inverse enabled
IEC958 In Valid muted
IEC958 Loop muted
IEC958 Out To DAC muted
IEC958 Output enabled

Readport produces the following output:
[root@draak ttonino]# ./readport 0xcc00 0x40
addr = 0xcc00, size = 64
00: 02 00 01 00
04: 00 0c 00 00
08: 13 00 29 00
0c: 00 00 01 08
10: c0 00 00 00
14: 00 00 a0 00
18: 00 00 08 00
1c: 00 00 fe ff
20: 10 40 c8 00

3c: 00 00 00 00

Then, I unloaded all Alsa related modules and loaded cmpci. Now, cmpci 
from 2.4.17 doesn't work: it emits a high pitched tone on the analog 
output instead of playing audio. I rebooted and cmpci works again. While 
playing the same mp3 through the 2.4.17 kernel driver:

[root@draak ttonino]# ./readport 0xcc00 0x40
addr = 0xcc00, size = 64
00: 01 00 02 00
04: 46 62 00 00
08: 1c 00 09 00
0c: 00 00 02 08
10: c0 00 00 00
14: 00 00 80 00
18: 00 00 08 00
1c: 00 00 fe ff
20: 10 40 c0 00
24: 01 0d 00 04
28: ff ff ff ff
2c: ff ff ff ff
30: 00 00 00 00
34: 00 00 00 00
38: 00 00 00 00
3c: 00 00 00 00

No options were given to modprobe, and no mixer settings changed. I 
mailed the exact build options for the module earlier (2 speakers, 
legacy devices enabled).

Cheers,


Thomas
