M-Audio Revolution 5.1 + oss + mpd

Hi, all.
What should I write in mpd.conf if I want to use volume control in Sonata and headphone output on my Revolution 5.1 with oss?

Did you ever figure out how to control a specific volume control with mpd + oss4?

Having sound distortions in games with M-Audio Revolution 7.1

I'm having sound distortion problems with a couple of games. I think this started a few OS X updates ago, but not sure which one. Two known games are Quake 3 and Quake 4. When I run either of them, the sound is deep and distorted.
I'm sure an update of OS X broke m-audio's revolution driver. I currently have driver version 1.4.1. I only have distortions when sending sound output to my sound card. Sound sent to internal speaker comes out fine. I also tried with a freshly created user and freshly reinstalled driver & prefs. Same problem.
I've tried M-Audio's site with no luck for solutions. It's been a year or so since they have updated it.
Is anyone else having similar experiences with their M-Audio Revolutions?

M-Audio Revolution 7.1 PCI Static in speakers

I have a Blue and White Power Mac G3 with the DayStar 600 mhz G4 processor upgrade, M-Audio Revolution 7.1 surroundsound PCI card and Creative Labs Inspire 7.1 surroundsound speakers and I'm running OS X 10.4.4. My speakers sound fine in stereo only mode but the minute I turn on the surroundsound I get this nasty cracking type of static in the speakers. The surroundsound works and they sound good inbetween the cracking but the cracking just won't go away. I've had these speakers and sound card and processor for about a year or so now and they've been doing this the whole time. I download every driver update that comes along hoping that each one will be the one that fixes the problem but no such luck. Has anybody else out there had this problem? Or had this configuration with no problem? Or better yet, had the problem and found the solution?

Substitute for M-Audio Revolution 7.1

Hello-I'm planning on purchasing a new 24" 2.8 GHz iMac; one problem I think I'm going to have is somehow connecting the new machine to my Klipsch ProMedia Ultra 5.1 speakers. I presently use an M-Audio Revolution 7.1 in my old G4 to hook up to this speaker system; works great.
Is there an external box of some kind (other than a home theater receiver and lots of adapters) that will allow me to connect the iMac's digital out mini jack to this speaker set? (It has the traditional three 1/8" cables, to hook up (1) front R/L, (2) surround R/L, and (3) subwoofer).
I may have to use an audio receiver to do this; but perhaps there's an interface available that I don't know about . . .thanks in advance for any suggestions.

Well, I guess I can now answer my own question; I've discovered the Griffin FireWave, a single box with FireWire 400 in (and a 2nd FW400 pass-through jack), and 5.1 audio out, via the 3 1/8" stereo jacks that will connect to my speaker set.
Picked one up on eBay for $60.00. No AC wall wart, either; it supposedly gets enough power from the FW port. I'll post on how well it works once I get it hooked up.

Xp 64 m audio revolution drivers?

any one seen the xp 64 m-audio revolution drivers out there? or anything compatible? It sucks that my xp 64 doesn't have sound

The m audio sound card is suppose to be better for sound quality. But I guess if I use the spdif it wouldn't make difference. or would it?

I have mine set to plug:plugequal as I use an equalizer with alsa, but when I set it to default it works fine, try that.
That didn't work out.

[SOLVED] Problem with MPD and ALSA

Hello, I'm having problems with mpd using alsa output.
My alsa system works, I can play mp3 using mplayer -ao alsa, and flash plugin plays sound, my user (and also mpd user)is in the audio group.
But then mpd can't open the alsa device.
If I tell mpd to autodetect audio, it can't find anything:
(Running as root to see output, if using /etc/rc.d/mpd start, it just fails)
output: No "audio_output" defined in config file

I tried with different device and mixer settings and the error is always the same. It can't open alsa device.
Any Ideas?
Thank you.

Check that mpd is really being run as the mpd user, and that id lists audio for the mpd user. Also post your whole mpd.conf and the output from amixer when running as the user you run mpd as.

Mpd and ncmpcpp

well I installed ncmpcpp, but when ever I try to run it I get this:
Cannot connect to mpd: problems connecting to "localhost" on port 6600: Connection refused
I have no clue what mpd was/is, so I installed it.. and ran "mpd"
unable to bind port 6600: Address already in use
maybe MPD is still running?
I am not familiar with mpd so I dont know what to do... I tried searching around but didnt find anything that solved my problem. Thankshave

Oh dear.. An update fixed the problem indeed, thank you.
HilmTye wrote: if you're starting mpd as a system service, then your user's config won't be used
You're right.. I just read the wiki more carefully. Indeed, I would like to run it for my user, so systemd is not
the best option for me. But I still have trouble.. The problem is that I can't autostart it the way it mentions
in the wiki. My mpd files are as follows:
jorge@flamingo:~$ ls ~/.mpd
mpd.conf mpd.db mpd.log mpd.pid mpdstate playlists
I tried this as per the wiki:
jorge@flamingo:~$ cat ~/.profile
# MPD daemon start (if no other user instance exists)
[ ! -s ~/.mpd/mpd.pid ] && mpd
but it didn't work. mpd was not running after reboot.
Then I tried /etc/profile:
jorge@flamingo:~$ cat /etc/profile
# /etc/profile
#Set our umask
umask 022
# Set our default path
PATH="/usr/local/sbin:/usr/local/bin:/usr/bin"
export PATH
# Load profiles from /etc/profile.d
if test -d /etc/profile.d/; then
for profile in /etc/profile.d/*.sh; do
test -r "$profile" && . "$profile"
done
unset profile
fi
# Source global bash config
if test "$PS1" && test "$BASH" && test -r /etc/bash.bashrc; then
. /etc/bash.bashrc
fi
# Termcap is outdated, old, and crusty, kill it.
unset TERMCAP
# Man is much better than us at figuring this out
unset MANPATH
export GPODDER_HOME="/home/jorge/Applications/Application Data/gpodder"
# MPD daemon start (if no other user instance exists)
[ ! -s ~/.mpd/mpd.pid ] && mpd
but it didn't work either.
In both cases, if I try to run mpd again from the terminal, I get:
jorge@flamingo:~$ mpd
server_socket: bind to '0.0.0.0:6600' failed: Address already in use (continuing anyway, because binding to '[::]:6600' succeeded)
and then mpd works.
Any ideas on how to startup mpd automatically on boot without systemd?

OSS Problem

I recently re-installed Arch Linux with OSS instead of ALSA because I had problems with ALSA. OSS seems to detect everything fine, and osstest outputs sound through my speakers and headphones.
The problem is that I can't get any other app to play sound. It's my first time using OSS ans ossxmix, so I'm confused when I see the buttons. I tried many random things but none make sound come out.

A screenshot of my ossxmix: Linky
Note: You can see that MPD is working properly, but no sound come out.
Another thing I noticed when doing more tests, it that osstest doesn't always output sound. What I mean is that I run it 2 or 3 times in a row, and it will play sound randomly with no apparent reason. The text output is the same, too... The first time I ran it (after installing and before rebooting), it always worked and switched the sound outpout when I plugged my headphones.
It seems the reboot broke my sound
Any help appreciated.
Update:
I rebooted again and watched if OSS gave any error message. Apparently, I didn't saw he complained about "Unknown HDA Codec". Where can I get the exact error? What am I missing?

I guess I'll have to google those errors and see what I can find.
Also, I don't think I'll have to configure the apps to work with OSS, because all my apps show up correctly at the bottom of ossxmix. And I'm not using KDE, so that isn't the problem.

Mpc/gmpc will not update mpd database

As per thread title. I've installed mpc following the single user setup instructions. All the clients I've tried seem to connect to it normally, but I can't get them to update the database.
mpc output:
[jewdozer@OKW ~]$ mpc update / --wait
Updating DB (#4) ...
volume:100% repeat: off random: off single: off consume: off
gmpc appears to update normally, but the files don't show up in the database. ncmpcpp puts the last update at hours ago, presumably when mpd was first started.
This is my /etc/mpd.conf file:
[jewdozer@OKW ~]$ cat /etc/mpd.conf
music_directory "/home/jewdozer/Musik"
playlist_directory "/var/lib/mpd/playlists"
db_file "/var/lib/mpd/db"
log_file "/var/log/mpd/mpd.log"
error_file "/var/lib/mpd/mpd.error"
pid_file "/var/run/mpd/mpd.pid"
state_file "/var/lib/mpd/mpdstate"
user "mpd"
The files never show up in the db file, and the log and error files are empty.
Ideas?

OSS *sometimes* has no sound

OSS is being really weird for me. When I first boot my system the sound never works. I'll go play with ossxmix a bit but ultimately change nothing, and sometimes it will randomly work, sometimes not. Sometimes I'll run an osstest and it will work and then the next one after does not work at all. Ultimately, really random and weird behavior.

For example, before I started typing this post it wasn't working. Now it's working fine. Ahhhh!
If it helps at all, alsa does not have any problems on this system. I'd love to be able to finally get OSS working though.

I should have asked earlier, but you have blacklisted the soundcore module (which loads Alsa) correct? Or they would race to get the sound card.
Also,I noticed that your devices are HD Audio and USB. The wiki says that support for usb and hd is experimental (read buggy).
EDIT: But then again, this website says that Intel HD Audio and Intel AC'97 are both supported. Go figure !

MPD and Jack

Hej,
I am trying hard to get mpd running with jack, but am constantly failing. Starting mpd it says "successfully detected a jack audio device" and everything looks fine, except i cannot play any file. When i try that with mpc i receive an error "Problems opening audio device". In the mpd logfile appears sth similar:
Oct 24 20:23 : output: Failed to open "default detected output" [jack]: Failed to connect to JACK server
Oct 24 20:23 : player_thread: problems opening audio device while playing "000 neue 000/Eddie Vedder/Into the wild/01 - Setting Forth.mp3"
Any ideas on how to solve this?
I am able to play sounds through jack with aplay, so my .asoundrc should be fine
thanks in advance

Yeah, and with the first way (direct mpd-jack-output) there is the problem.
Mpd starts fine, but if you wanna play any audio over your favourite client (ncmpcpp in my case), a error-msg is written to the log.
Something like the ones calle posted.
But ... ... I am going to increase the verbosity level of mpd. *idea* :-)
EDIT:
The Result
Nov 11 14:11 : decoder: audio_format=44100:24:2, seekable=true
Nov 11 14:11 : output: Failed to open "default" [jack]: Failed to connect to JACK server
Nov 11 14:11 : player_thread: problems opening audio device while playing "Hidden_-_Song.mp3"
This is the output with the highest verbosity-level.

[solved] I hear audio 1s after playback starts - ALSA & ALC888 S/PDIF

Hello,
I run 64bit Arch Linux, my soundcard is a Realtek ALC888 (HDA ATI SB according to alsamixer) and I use ALSA (alsa-lib 1.0.21.a-1).
The back of my computer looks like this:
I have a YAMAHA RX-V596RDS AV Receiver connected to my sound output via a TOSLINK (S/PDIF or Optical Cable) connector.
My alsamixer looks like this (edited to fit small screen):
I used aadebug to get some info about my setup: output
I have two problems with my setup:
1. Whenever I start playback - be it mpd, mplayer, vlc, flash in ff, aqualung or audacity - the playback will start instantly, but I will only start hearing the output when one second has passed. (So I won't hear the first second at all.)
This also happens when I use the RCA Jack to connect my AV Receiver.
However, if I unmute "Front" and increase volume for it in alsamixer and connect my headphones to the light green (stereo) jack output (on top left in photo above) and tell audacity to use hw:0,0 ("ALSA: HDA ATI SB: ALC888 Analog") as output, I will hear the sound in my headphones *instantly* when playback starts.
When I 'mpd next' the same delay of ~1 second will happen. However I noticed that if I pause audio playback sweep (audio editor) and very quickly continue playback, there will be no gap and no 'loss of audio'.
I suspect, that dmix goes into a stand-by state, whenever audio stops. Can I force dmix to have a longer timout or none at all?
2. I can't get Audacity to playback audio together with other applications. mpd and mplayer and flash in ff and vlc will play audio at the same time, but audacity won't. If I start audacity while mpd is playing, there won't even be the option to select "hw:0,1", "iec958", "spdif" or "default". If I use any other device (like dmix), it will play using analog (I can hear it in my headphone).
If I start audacity, then start mpd and then try to playback in audacity (using any of the devices "hw:0,1", "iec958", "spdif" or "default"), I get following error message repeatedly:
Expression 'ret' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 1027
Expression 'AlsaOpen( hostApi, parameters, streamDir, &pcm )' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 1059
Any one having these problems? Anyone having ideas what the reasons might be?
Thanks

I don't know if this will help but i used to have a similar problem when i switched to musicmanager as my default music player, (i also have the same soundcard)
When connected to my receiver via optical out there would be a initial delay of around a second everytime when playing a new song, although there was no delay through my laptop speakers.
What worked for me was adding esd to my daemons array
