I have an Ensoniq 1371 board on a Linux box running
kernel 2.4.18. Everything seems to be OK, in that all
the drivers are loaded and I can play sounds all
right. There are a few issues though, which were not
present when using ALSA 0.5:
1) The board is reset to some (default, I guess)
values on rebooting, despite of the fact that I have a
post-install snd-mixer /usr/sbin/alsactl restore
line in my /etc/modules.conf. This is not a big deal,
for I can invoke the alsactl command from one of the
local boot files, but I wonder why the post-install
line doesn't seem to be doing anything?
2) When doing (as root)
/usr/sbin/alsactl restore
the following message is printed:
alsactl: set_control:960: Cannot write control
'3:0:0:IEC958 Playback Mask:0' : Operation not
permitted
I have no clue what this means. The relevant entry
in /etc/asound.state reads
control.33 {
comment.access 'read write'
comment.type IEC958
iface PCM
name 'IEC958 Playback Mask'
value ffffffff00000000000000000000000
0000000000000000000000000000000
0000000000000000000000000000000
0000000000000000000000000000000
0000000000000000000000000000000
0000000000000000000000000000000
0000000000000000000000000000000
0000000000000000000000000000000
0000000000000000000000000000000
0000000000000000000000000000000
0000000000000000000000000000000
00000000000
}
I have used a few different values for the value
field, but they don't seem to make much of a
difference. I don't know what this IEC958 business is
all about, anyway; I would be happy if somebody can
enlighten me here, and let me know what are the
appropriate values to use.
3) This one is annoying. I am using Gnome 1.4.1,
and when I log in (from the Gnome display manager gdm)
if the board settings are the right ones (as stored in
my asound.state file) then the welcoming tune starts
playing all right, but gets interrupted half way
through.
On immediately checking the board settings I
notice that they are reset to their default values, as
when rebooting. Such values mute most channels - in
particular, the PCM channel. I can invoke alsactl
restore by hand from an xterm all right, and from that
point onwards the sound works fine under Gnome.
I am at a loss so as to why the board is reset
when starting my Gnome session. I am aware that this
is really not an ALSA question - although it did not
happen with the ALSA 0.5 drivers, and my Gnome
configuration has remained unchanged. Anyway, any
pointers on this issue would be greatly appreciated.
