[Followup to myself]
With the latest changes to the pcm driver, a downgrade of channel.c to
1.8 doesn't help any more:
I cannot hear anything while playing something (in my case with mpg123).
A verbose output of mpg123 shows me that the application seems to hang
after a few write()'s to the sound device (with no sound output). There
also doesn't seem to be any interrupt activity on the pcm interrupt.
Two days before (but with rev 1.8 of channel.c) I could play any pcm file
I have with only some noise at the end if I interrupt mpg123 with ^C.
Here the latest configuration information (I can post full output if
requested).
Kernel config:
[...]
device pcm0
device sbc0
options PNPBIOS
[also without PNPBIOS but with
device sbc0 at isa? port 0x220 irq 5 drq 1 flags 0x10
no difference]
dmesg output from a verbose boot:
sbc0: <ESS ES1869> at port 0x220-0x22f,0x388-0x38b,0x330-0x331 irq 5 drq 1,0 on
isa0
pcm0: <SB DSP 3.01> on sbc0
pcm: setmap 30000, ff00; 0xcd4b5000 -> 30000
pcm: setmap 40000, ff00; 0xcd4c5000 -> 40000
