ESS 1788 not working on my Compaq Presario 1080 notebook...

[James N. Grace]

My kernel config is as follows:

device pcm
device sbc0 at isa? port 0x220 irq 5 drq 1 flags 0x15


"more /var/run/dmesg.boot" produces the following related output:

sbc0: <ESS 688> at port 0x220-0x22f irq 5 drq 1 flags 0x15 on isa0
pcm0: <ESS 18xx DSP> on sbc0


"cat /dev/sndstat" produces the following output:

pcm0: <ESS 43434 DSP> at io 0x220 irq 5 drq 1:5 bufsz 4096 (1p/1r/0v channels duplex)


"cat 11khz_test.au > /dev/dsp" produces almost recognizable sound.

"cat 16khz_test.au > /dev/dsp" recognizable.

"cat 22khz_test.au > /dev/dsp" fast, unrecognizable.


Using "mpg123" to play an MP3 file produces no sound at all and produces
the following error:

pcm0:play:0: play interrupt timeout, channel dead


Using "mpg123 --8bit" to play an MP3 file produces strange, garbled sound
and produces the following error:

pcm0:play:0: play interrupt timeout, channel dead


Music CDs play fine and the "mixer" application seems to work properly.


Any ideas?
