next in thread | raw e-mail | index | archive | help
I have NOTE-PC which has ESS 1869 sound chip.
NEC MobioNX MMX Pentium120MHz
[kernel configuration, this on-board card is not PnP]
device pcm0
device sbc0 at isa? port 0x220 irq 5 drq 1 flags 0x13
% cat /dev/sndstat (under 5-current)
FreeBSD Audio Driver (newpcm) May 21 2000 17:43:39
Installed devices:
pcm0: <ESS 1869 DSP> at io 0x220 irq 5 drq 1:3 (1p/1r channels)
----------
After split up ess and sb code at 2000/03/28 by Cameron Grant-san,
if I once suspend and resume NOTE-PC, I could not play MP3 file
after resume.
boot up kernel
<--- I can play MP3 file
suspend
resume
<--- I could not play MP3 file anymore
mpg123 was run but increase count and no sound
So I created quick hack patch for ess.c. Sorry I don't know why
new ess.c code does not support above situation, what happen after
resume....
If I have time, I will check it.
P.S.
I have another problem under ESS1869. If I set volume by
/usr/sbin/mixer command. But it was not set correctly.
% mixer vol 10
Setting the mixer vol to 10:10.
~~ ~~
% mixer vol
Mixer vol is currently set to 9:9

Thank you.
