I got this tip on the list yesterday, and that was to start alsamixer and
mark line-in as capture. Then go furthest to the right, until you find a
device called capture and hit space over that to enable capture on it. That
fixed my problems ...

I did not have any success installing ALSA and running alsamixer returns

alsamixer: function snd_ctl_open failed for default: no such device

"No such device" usually means the device file exists but
there is no driver associated with that file. /dev/dsp
is normally a sym link to dsp0 . For ALSA to associate
a sound card with dsp0, you need a line in modules.conf for:

alias snd-card-0 snd-XXX

but I don't see this in the modules.conf segment you sent.

Go to: http://www.mythtv.org/docs/mythtv-HOWTO-7.html#ss7.1
and look over the section on how to edit your modules.conf .

-- bjm

Based on the settings that I provided in the first posting (modules.conf) what would be the settings then that I should add into my modules.conf to get this to work?

Just adding

alias snd-card-0 snd-XXX

certainly doesnt work and going through those docs you mentioned is not clear (what should XXX be?) and I still cant get it to work. However, the original setting I provided does allow sound through xmms etc?

I would be very greatful if someone could provide/suggest the exact settings needed in my modules.conf, based on what is there now using the sb sound driver.

Thanks

<br>

Following the instructions to the letter on the ALSA site for this card I changed modules.conf as follows:

alias eth0 tulip
alias char-major-81 bttv
alias char-major-195 nvidia

# ALSA portion
alias char-major-116 snd
alias snd-card-0 sb

# module options should go here
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || :
pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || :
options sound dmabuf=1
options opl3 io=0x388
alias synth0 awe_wave
post-install awe_wave /bin/sfxload /etc/midi/GU11-ROM.SF2
options sb isapnp=1


# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0

# card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss


And I still can get sound from xmms, and I hear the driver getting loaded, and lsmod shows the following:

[root@localhost root]# lsmod
Module Size Used by Tainted: P
snd 40260 0 (autoclean)
mousedev 5236 1 (autoclean)
input 5632 0 (autoclean) [mousedev]

iptable_filter 2316 0 (autoclean) (unused)
ip_tables 14488 1 [iptable_filter]
autofs 12148 0 (autoclean) (unused)
nfs 74424 2 (autoclean)
lockd 53968 1 (autoclean) [nfs]
sunrpc 77084 1 (autoclean) [nfs lockd]

uart401 8036 0 [sb_lib]
sound 70132 1 [sb_lib uart401]
soundcore 6116 5 [snd sb_lib sound]
ext3 64704 2
jbd 47860 2 [ext3]


But I still get the following

[root@localhost root]# aplay /dev/dsp
aplay: main:480: audio open error: No such device

for /dev/dsp, dev/dsp0, dev/dsp1 etc

If anyone knows what the correct settings shoudl be, I would be greatful.

I also followed the complete ALSA instructions for the AWE 32 and this modules.conf will not load snd-sbawe:

alias eth0 tulip
alias char-major-81 bttv
alias char-major-195 nvidia

# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-sbawe

# module options should go here

# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0

# card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss


Running modprobe snd-sbawe produces...

[root@localhost root]# modprobe snd-sbawe
/lib/modules/2.4.20-18.9/kernel/sound/isa/sb/snd-sbawe.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
/lib/modules/2.4.20-18.9/kernel/sound/isa/sb/snd-sbawe.o: insmod /lib/modules/2.4.20-18.9/kernel/sound/isa/sb/snd-sbawe.o failed
/lib/modules/2.4.20-18.9/kernel/sound/isa/sb/snd-sbawe.o: insmod snd-sbawe failed



Any suggestions would be greatfully appreciated.

Thanks again

Just a quick note -- I seem to remember getting a similar error when I
forgot to run "./snddevices" in the alsa-driver-0.9.4 directory.

Thanks. I have now moved the Hauppaug card into a Shuttle SN41G, which is where I eventualy want to run a 250 card, so next week I will be working on getting MythTv working on it. Already dealing with something I didnt expect, NO VIDEO IN on the Shuttle SN41G. ARGH. Been reading all sorts of posts elsewhere and cannot get the surround/center outs to act as line in and currently running the sound into the mic. Will try to rewire the cd in on the mb as a line in. Then I can return to installing MythTV on the Shuttle and we will se how far I get until I can get the pvr-250
