M-Audio Delta DiO 2496 sound card setup with Fedora Core 3 linux and ALSA

Got driver/module info from http://www.alsa-project.org/alsa-doc/

FC3 came with alsa. Confirmed with:

modinfo soundcore

Inserted modules for maudio 2496 with:

modprobe snd-ice1712;modprobe snd-pcm-oss;modprobe snd-mixer-oss;modprobe snd-seq-oss

Actually these modprobe's were not necessary for future reboots (Fedora Core 3)

Viewed with:
lsmod

Adjusted volume with 'alsamixer'.
Saw "Card: M Audio Delta DiO 2496"
"Chip: ICE1712 - multitrack"
"Item: IEC958"

Read how to use alsamixer: man page

M key toggles muting

Add fedora-extra to yum repository:

The best way to use Fedora Extras is via yum. Add a file (e.g. fedora-extras.repo) in your /etc/yum.repos.d dir with following

content:

[extras]
name=Fedora Extras - $releasever - $basearch
baseurl=http://download.fedora.redhat.com/pub/fedora/linux/extras/$releasever/$basearch/
gpgcheck=1
gpgkey=http://download.fedora.redhat.com/pub/fedora/linux/extras/
RPM-GPG-KEY-Fedora-Extras

[extras-testing]
name=Fedora Extras Test Updates - $releasever - $basearch
baseurl=http://download.fedora.redhat.com/pub/fedora/
linux/extras/testing/$releasever/$basearch/
gpgcheck=1
gpgkey=http://download.fedora.redhat.com/pub/fedora/linux/extras/
RPM-GPG-KEY-Fedora-Extras

[extras-debug]
name=Fedora Extras - $releasever - $basearch - Debugging packages
baseurl=http://download.fedora.redhat.com/pub/fedora/linux/extras/$releasever/$basearch/debug/
gpgcheck=1
gpgkey=http://download.fedora.redhat.com/pub/fedora/linux/extras/
RPM-GPG-KEY-Fedora-Extras

Import the authentication key:

You will also want to make sure you've imported this:

http://download.fedora.redhat.com/pub/fedora/linux/extras/RPM-GPG-KEY-Fedora-Extras

key into your rpm database. Use this command to import it:

rpm --import http://download.fedora.redhat.com/pub/fedora/linux/
extras/RPM-GPG-KEY-Fedora-Extras

Installed alsa-tools (from Fedora Extras) to get envy24control tool (gui sound mixer for M-Audio)

yum install alsa-tools

yum install xmms-cdread

[still cant read cdrom]



============

Make xmms play mp3's:

get xmms-mp3 from DAG repository.

added /etc/yum.repo.d/dag.repo

Contents of dag.repo:

[dag]
name=Dag RPM Repository for Fedora Core
baseurl=http://apt.sw.be/fedora/$releasever/en/$basearch/dag
gpgcheck=1

Added dag key:

[root@mythtv yum.repos.d]# rpm --import http://dag.wieers.com/packages/RPM-GPG-KEY.dag.txt

yum install xmms-mp3

List soundcards:

[root@mythtv ~]# cat /proc/asound/cards
0 [M2496 ]: ICE1712 - M Audio Delta DiO 2496
M Audio Delta DiO 2496 at 0xa000, irq 11

(soundcard 0 is Maudio 2496)

===========
tried various suggestions from the internet: basic /etc/asound.conf and .asoundrc files.
revert to default (removed /etc/asound.conf, .asoundrc files). /etc/modprobe.conf contains its orig lines:

[root@mythtv ~]# cat /etc/modprobe.conf
alias eth0 8139too
alias snd-card-0 snd-ice1712
options snd-card-0 index=0
install snd-ice1712 /sbin/modprobe --ignore-install snd-ice1712 && /usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-ice1712 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-ice1712
alias usb-controller ehci-hcd
alias usb-controller1 uhci-hcd
alias ieee1394-controller ohci1394


===========

Got 44.1KHz mono wav off net. BUSTIN.wav:
goog search "wav 44.1khz"

aplay -d default BUSTIN.wav (WORKS! :-)

NOTE: I had to reboot once before aplay worked.

[root@mythtv ~]# aplay -D default bustin.wav
Playing WAVE 'bustin.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono

[ xmms player still complains that it cant use sound device ]
Was able to fix xmms:
* Preferences, Under "Output plugin", plugin name "ALSA 1.2.10 output plugin [libALSA.so]", Click "Configure" button and set

"Audio device" to "default" (was set to hw:0,0 during troubleshooting). Left Mixer unchecked. Then was able to play bustin.wav

with xmms.

then, audio cd's wouldn't play. enabled cd reader, disabled cd audio player per internet instructions. cd appears to
be playing visually, but no sound.

also was able to use envy24control mixer sliders by changing patchbay to spdif out(L)=Digital Mix L, and spdif out(R)=Digital Mix R

After changing envy24ctrl to "Digital Mix L/R", xmms could play Audio CDs :-)
Adjusted Digital mixer sliders in envy24control to my prefferred volume levels for listening.

Setting up xmms for Audio CD playing:

Open the xmms media player. Right click in xmms and select Options>Preferences>Audio I/O Plugins

Select 'CD Audio Player' and uncheck the 'Enable plugin' button. Select 'Audio CD Reader' and 'enable' it. Select 'Configure' for

audio CD Reader and ensure the correct device is selected you want to play CDs from (/dev/hdx where x is a,b,c, or d, or /dev/scd0

etc if it is a SCI device)

Now save the options and right click on xmms and select 'Play File' a dialogue box will open. Enter the device name in the selection

box, for example /dev/hdc and click 'OK'

The CD will now play, and if you are online and cddb was enabled in the plugin options you will see the CD track names appear in the

xmms playlist. The next time you put in a CD you will not need to 'Select File' Just press the 'Play' button and it should start

playing.

[ in my system, /dev/hdb is the cdrom drive (a HP dvd burner actually) ]

After all this was working, checked what alsamixer said the setting were:

Along the sliders, it said "Digital" and "Digital" instead of "PCM out" and "PCM out". So "Digital" seems to be the right

setting.

then, tested mp3 playing (note, that xmms-mp3 was yum/installed earlier, see above). loaded file and it played :-)


==========

alsamixer:


Digital, Digital


envy24control:
Patchbay: spdif out(L)=Digital Mix L, spdif out(R)=Digital Mix R
Hardware settings: Master clock=44100, Locked(unchecked), Reset(checked), Vol Change rate=140,

Note, despite what some people said on the internet, soundcard seems to work fine while sharing IRQ with eth0:

[root@mythtv ~]# cat /proc/interrupts

0: 1811760 XT-PIC timer
1: 991 XT-PIC i8042
2: 0 XT-PIC cascade

9: 0 XT-PIC acpi
10: 105175 XT-PIC uhci_hcd, uhci_hcd, ohci1394, radeon@pci:0000:01:00.0

12: 14160 XT-PIC i8042
14: 14989 XT-PIC ide0
NMI: 0

(Notice ice1712 is sharing irq11 with eth0 and other stuff)
