ALSA: Trying to reset sound card

I have ALSA and Pulseaudio installed on my machine. When I play with
mplayer -ao pulse
It generally works fine even when the audio device gets stuck (just a bit glitch). However, if I play with
mplayer -ao alsa
When the audio device gets stuck, it gives me
[AO_ALSA] Write error: Broken pipe
[AO_ALSA] Trying to reset soundcard.
It's thrilling when the soundcard is reset and there is a sudden increase in the volume. And I'm curious why the soundcard got reset.
I'm also wondering what happens when I specify ALSA as the audio output driver with Pulseaudio installed. Does Pulseaudio act as a proxy between ALSA and the actual soundcard hardware, or is it simply ignored?

Hmm what do you mean the audio device gets stuck? does it stop playing or start to stutter or what?
Maybe it has problems when being reinitialized, set
exit-idle-time=-1
in /etc/pulse/daemon.conf which should prevent it from being unloaded
Regarding your question, it will act as a proxy when you install pulseaudio-alsa and (lib32-)alsa-plugins (and your ALSA application uses the default device defined by the /etc/asound.conf, created by pulseaudio-alsa) otherwise it will be ignored, thus blocking the device from being used by other clients (or if pulse-applications are active, blocking ALSA only clients from connecting).

Sound problems, ALSA can't find sound card at boot

Sometimes, my sound randomly drops out, and I can't get it back until I reboot. Even when I reboot, 1/20 times, it will not be back.
When I watch stuff on youtube, sometimes the sound just drops out. Nothing gets muted. My audio player can't produce sound.
If I do
lsmod | grep snd
I'll see the some output.
When I reboot and try to play music from Quodlibet, I'll get an error like this:
Output Error
GStreamer output pipeline could not be initialized. The pipeline might be invalid, or the device may be in use. Check the player preferences.
"lsmod | grep snd" will have NO output and when I try to start alsamixer:
[xz@gestalt ~]$ alsamixer
cannot open mixer: No such file or directory
I can't figure out what's going on, and googling has just led me to various not-completely-related posts on this board... what could be the problem?
EDIT: A few more things to note--
I have alsa in my daemons list in rc.conf
I'm part of the "audio" groups.
soundcore is not blacklisted

Audio devices aren't even mentioned. I noticed when I tried to boot up that I get an error like "sound card not detected." Why would arch suddenly not be able to find a soundcard? It looks like it almost has nothing to do with my ALSA configuration, and has more to do with my sound card not being found at all in the first place....

No sound with alsa and integrated Intel sound card, any advice???

I just got a new computer, erased the OEM windows install and installed Arch linux with xfce. I have an Integrated HDA intel sound card with Realtek ALC888 chip
Sound worked just fine in the windows install, so I know the card and speakers work.
I installed alsa and made sure to unmute PCM and Front speakers. Unmuting all of the entries didn't help. Any advice would be greatly appreciated.

I am going through the wikiarticl on alsa as well, but if anyone can point out what the issue is hear I would greatly appreciate it.

Hmm. I have an onboard Intel sound chipset as well.. I noticed your rc.conf doesn't have "snd-hda-intel" in the MODULES array; make sure you add that.
I never figured out how to read the right side of lsmod's output, so I'll assume that, despite having the snd-hda-intel module, you haven't enabled it yet. Try (as root or through sudo) `modprobe snd-hda-intel`. It may need underscores instead of hyphens; they seem to be interchangeable.

No sound with ALSA, using an intel sound card

Hello !
I have got a problem about sound on my computer. Indeed, my soundcard doesn't seems to be recognize by ALSA. It's weird, I'll show you. Well, my soundcard is :
lspci | grep Audio
00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) (rev 40)
Next, my sound modules loaded are
lsmod | grep snd
snd_hda_intel 21837 0
snd_seq_dummy 1479 0
snd_seq_oss 29240 0
snd_seq_midi_event 5516 1 snd_seq_oss
snd_seq 50562 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi_event
snd_seq_device 5281 3 snd_seq_dummy,snd_seq_oss,snd_seq
snd_pcm_oss 39509 0
snd_hda_codec 74609 1 snd_hda_intel
snd_mixer_oss 17730 1 snd_pcm_oss
snd_hwdep 6222 1 snd_hda_codec
snd_pcm 72321 3 snd_hda_intel,snd_pcm_oss,snd_hda_codec
snd_timer 19537 2 snd_seq,snd_pcm
snd 58906 10 snd_hda_intel,snd_seq_oss,snd_seq,snd_seq_device,snd_pcm_oss,snd_hda_codec,snd_mixer_oss,snd_hwdep,snd_pcm,snd_timer
soundcore 6161 1 snd
snd_page_alloc 7361 2 snd_hda_intel,snd_pcm
Then, I want sound. I use alsaconf, of course, and I can choose my soundcard in a list (the other choice is "legacy"). I answer yes to the question "Do you want to modify /etc/modprobe.d/sound.conf [...] ", and then, during a few seconds :
Loading driver...
:: Saving ALSA Levels [BUSY]
/usr/sbin/alsactl: save_state:1519: No soundcards found... [FAIL]
It's eerie, I found my card in the list, and then not >_<
Then, alsamixer say me : "cannot open mixer: No such file or directory".
Here is my /dev/snd directory :
lsi /dev/snd
total 0
crw-rw---- 1 root audio 116, 3 Mar 4 15:06 seq
crw-rw---- 1 root audio 116, 2 Mar 4 15:06 timer
/dev/dsp and /dev/mixer don't exist.
So, to summarize, I finally don't have sound in my computer (I never had since I made it). I also tried using OSS, but it didn't work as well.
So I need you help, if you need some more informations, I can get them. Thank you very much !

Issue with ALSA softvol and reloading sound card module

I'm using a Chaintech AV710 card with the snd_ice1724 module as a driver. The core issue is that sometimes when this module is loaded during startup (or every time after a suspend), it will play nothing but very loud static. To fix this, I simply reload the module. This fix worked fine for me while I used pulseaudio: I would just kill pulse, reload the module, and start pulse after every suspend. Now, however, I'm using a system that involves an ALSA softvol plugin. The softvol device is being used by JACK: jackd -d alsa -d softvol. When I reload the module using this setup, the softvol control I set up becomes locked at 100%. amixer reports "Invalid command!" for sset Master2 10%. The audio will still play, but I can't figure out any way to reset it to make this control work again short of renaming the control, restarting jack, renaming the control back to the original name, then restarting jack again. Any help alleviating this issue on any of these fronts would be appreciated. Relevant asound.conf sections:
pcm.mycard {
type hw
card AV710
device 1
rate 44100
channels 2
format S32_LE
pcm.softvol {
type softvol
slave.pcm "mycard"
control {
name "Master2"
card AV710
ctl.softvol {
type hw
card AV710

[Solved] Alsa Sound Card Numbering Not Persistant Between Boots

Hello,
I'm having trouble with alsa and my multiple sound cards. Sometimes when I boot, I get the following output from "aplay -l"
**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: ALC889A Analog [ALC889A Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: SB [HDA ATI SB], device 1: ALC889A Digital [ALC889A Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 2: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
However, I also see this after other boots:
**** List of PLAYBACK Hardware Devices ****
card 1: SB [HDA ATI SB], device 0: ALC889A Analog [ALC889A Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: SB [HDA ATI SB], device 1: ALC889A Digital [ALC889A Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 2: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
Because the card numbering is not consistant, I'm having a great deal of trouble (if the card is 0, then I don't need an asoundrc, but if it's 1, I do). It also breaks my volume panel applet for the alsa card number to often change (volumeicon - from the AUR). Is there a way to force a certain device to always be card number 0?
Thanks for any help.

I'm completely new to writing udev rules; would the proper procedure be to write something like this:
DEVPATH=="/devices/pci0000:00/0000:00:14.2/sound/card*" ATTRS{number}="0"
or will that happen too late in the boot process (after the card has already been assigned a number)?
Perhaps it would be easier to work through alsa itself? I know I can get sound consistantly by calling out the card in asoundrc:
pcm.!default { type hw card SB }
ctl.!default { type hw card SB }
But this seems to disable dmix (software mixing). Is there a way to re-enable dmix from the asoundrc (and would that be easier than trying to work in udev)?

Sean

Sound Card

I have tried 2 different sound cards in 2 different PCI slots, and my computer never finds them. When i try to install the drivers (sound blaster) they say the device cannot be found on my computer. Also, as i mentioned in another post, WindowsXp doesnt seem my other LAN controller (the bottom one) Could like plug and play be off or something? Why wouldnt any of this stuff load up? Any ideas?
But i do have a "PCI Device" in other devices in the device manager, says its on PCI Slot 8. That means nothing to me i have no idea what this could be, cause its not letting me load the sound card drivers.

Quote
Did you disable to onboard sound
like rc23 said
Quote
tizzle specs please
like supershanks said
you will get more help and more accurate help then
but try removing card setting onboard sound on in bios first.
if all runs ok set on board sound to off. in bios.
reboot....
switch off.
insert card.
reboot . if not recognised by windows install manually under device manager.
if windows recognises install drivers from orig disc before updating you can then always roll back to original if an driver update fails.
you could check your soundcard in a friends machine first !
try another sound card !
just some ideas

Satellite A300 and Win7 - Strange problem with speakers\sound card

Hello everyone,
I am working on a - A300-1MO with win 7 ultimate 32 bit
In the last few days (since I have installed the Bluetooth driver but I dont think it matters), the sound card, and therefore the laptop speakers, switch from being mute to being active, sometimes in high volume.
It disturbs me a lot because my computer is making sounds while I am in classes (from apps running\web sites etc.). I almost got kicked out of class several times because of it.
I tried muting the sound card from the windows mixer and from the sound card application, it's no use.
I will appreciate any help.
Thanks a bunch
Roi.

Hi roibs,
> It disturbs me a lot because my computer is making sounds while I am in classes (from apps running\web sites etc.). I almost got kicked out of class several times because of it.
Maybe you should leave your computer at home and not play with it in your class ;)
Anyway, I would recommend disabling all Windows sounds in control panel. That means no sounds will be played while you navigate through the Internet or use the Explorer.
Check this!!!

KT880 Delta LSR doesn't support second sound card?

Hello,
I've just bought my new KT880 Delta board because of burning my old KT4V.
In my last configuration Ii had sound on bord (5.1) and one sound card added for microphone and headphones.
Now i can't force my KT880 Delta LSR to support two sound card on the same time. When I don't plug PCI card system support card-on-board.
But when I add this PCI card system dosen't see onboard card. In BIOS onbord card is turned on.
What should I do to solve my problem?
BRGDS
Max.

Quote from: Doctor Stu on 24-May-05, 04:34:01
maxisus, maybe the PCI card is conflicting with onboard?
have you tried the PCI sound card in another slot?
No, i didn't try. I thought that is no different witch pci slot you use.
Quote from: Doctor Stu on 24-May-05, 04:34:01
did you do a fresh install of windows when you replaced the mobo?
yes, i've formated hdd and installed all once again
Quote from: Doctor Stu on 24-May-05, 04:34:01
also KT880 probably needs more power than KT4V - if your PSU is now not powerful enough, some devices cannot start up correctly.
I have got 350 Watt - i bought new because of special 4-pin plug for CPU. In the shop gays sad PSU should be enought for my configuraction of pc.

Setting ALSA sound card system wide (rather than just in KDE)

Hi,
I've got an HTPC with an ATI Radeon HD 4350 graphics card running Arch x86. It has its own integrated sound card for outputting audio via HDMI, which is detected by ALSA as a separate device. I've managed to set it as the default audio device in KDE 4 (via System Settings). This allows applications such as Amarok and SMPlayer to properly output audio to the HD 4350's integrated sound card, but software such as Flash and MPlayer (from the command line) are still outputting audio to the motherboard's built-in sound card. How can I change this setting on a system-wide level? I've tried running alsaconf as root and adding
pcm.!default {
type hw
card 2
device 3
to ~/.asoundrc; I got the card and device numbers from aplay:
[htpc@exia ~]$ aplay -l

No, I haven't tried that. I'll give it a shot. Thanks for the tip!

ALSA is not detecting my M-Audio Delta 1010 sound card (x86-64)

Hi
I've been searching Arch forums and googling for my problem but I can't find a suitable answer.
I installed my M-Audio Delta 1010 sound card on this PC but ALSA doesn't get it to work.
Chipset envy24 / ice1712
On dmesg I find:
$ dmesg | grep -i ice1712

controlC0 and pcmC0 is not present!
So, what might be causing the probe error -5?
I really need to get this card working! :S
I have Arch up to date!
Hardware specs:
CPU: AMD FX6100
Board: Gigabyte (can't recall the model) with NVidia chipset
Thank you,

I have an m-audio delta 1010lt as well, it's a great card but it sits in my closet now because I "upgraded" to a motherboard that doesn't have legacy PCI slots. However, I'm pretty sure I remember the card working for me and being "plug and play" under arch with kernel 3.3 or newer. So some things I would consider:
Try checking IRQs, make sure nothing is overlapping.
Try using the LTS kernel, to see if it is kernel related, since ice1712 module should ship with almost any kernel => 2.6.26.
How many watts is the power supply? Sometimes insufficient wattage can result in drivers failing to load.
What other sound cards do you have installed? Have you tried blacklisting all of the other cards in your system using alsa-base.conf? This is a bit extreme, but might be a useful troubleshooting measure, as some people have had issues in the past with alsa indexing mutiple cards to the same slot number

[SOLVED] Software mixing on ALSA+USB sound card

I have cheap chinesse USB soud card. lsusb says its "Tenx Technology, Inc. TP6911 Audio Headset"
After arch installation sound was working about 2-3 reboots. Then i googled and deleted pulseaudio, and sound randomly working or not after reboots.
After a lot of research i got /etc/asound.conf like that:
pcm.!default {
type hw
card AUDIO
ctl.!default {
type hw
card AUDIO
"AUDIO" its name of card. Checked that. And now i had sound in 80% reboots.
After research i founded that i cant play 2 sounds at same time. (And youtube writes "error occured" for 90% videos).
Tested aplay (it never works):
>aplay /usr/share/sounds/alsa/Front_Center.wav
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
aplay: set_params:1239: Channels count non available
Then played sound in other program and in same time launched aplay:
>aplay /usr/share/sounds/alsa/Front_Center.wav
aplay: main:722: audio open error: Device or resource busy
So that mean i need software mixing.
Googled, and installed "alsa-oss" and did some random stuff with config
pcm.!default {
type hw
card AUDIO
slave.pcm "dmix"
ctl.!default {
type hw
card AUDIO
slave.pcm "dmix"
and now youtube working. I hear it. But now aplay says:
>aplay /usr/share/skype/sounds/CallBusy.wav
ALSA lib pcm_hw.c:1743:(_snd_pcm_hw_open) Unknown field slave
aplay: main:722: audio open error: Invalid argument
He dont like "slave" thing in config, but it helps. I tested 3 times, added "slave" and rebooted and youtube works. Without "slave" it not working.
And i still cant hear 2 sounds at same time. In google ALSA says like software mixing must work without config, if not then do bugreport.
Im in arch less then 7 days, before i had experience with ubuntu server only, so configuring ALSA is hard for me.
Can somebody help me configure software mixing?
Thank you.

Okay. I surfed your URLs and ended in http://alsa.opensrc.org/Dmix
Example /etc/asound.conf from 3 and 5 works great! Thank you!
If somebody will google Tenx Technology, Inc. TP6911 Audio Headset
Use /etc/asound.conf (you need create it)
pcm.dsp0 {
type plug
slave.pcm "hw:0"
ctl.mixer0 {
type hw
card 0
or
pcm.dsp0 {
type plug
slave.pcm "dmix"
hint {
show on
description "My dmix dsp0"
ctl.mixer0 {
type hw
card 0
both works for me.
=======
Aaaaand after 2 reboots everything is broken. Both configs not helping. aoss and alsaplayer don't make any sound.
5 reboots later sound again works.
=======
Okay, i know why i need reboot.
If you have same problem - do aplay -l, if your card not first - nothing will work. You need reboot until your card is first. I tryed to do my card always first, but then mixer dont work. And for make it work on every reboot looks like you need read 18 huge books about universe creation.

Usb Sound Card Playback Issues - Alsa [SOLVED]

Hey folks:)
Just want to say Archlinux is lovely and you guys are doing great work (if be it a little frustrating at times i might add)
My problem is that i can't configure my USB UA-25 sound card properly.
If i want to record with ardour, or hydrogen using JACK, everything is fine.
BUT.
If i want to play back a simple music file, or run 'youtube' for example, sound refuses to come out of my computer.
In system>preferences>sound the driver is set to ALSA.
How can i get sound to play back normaly through my externel sound card? I think Archlinux is trying to use my onboard laptop sound card.
Thanks!

fixed the probelm;
Had to reinstall alsa dirvers, removed all instances of 'usbaudio' from the modules. Reboot. modprobe snd-usb-audio. unmuted all mixers.
Selected alsa as the driver. Test. Yay! :"")

Sound card not being detected by alsa

I compiled a kernel using the /usr/src method as per the wiki page. However, I've been having some problems with ALSA. I compiled in ALSA and support for my card (I think I did at least) as modules. alsaconf finds my card fine, but alsamixer dies with this message:
alsamixer: function snd_ctl_open failed for default: No such device
I tried using strace on it:
open("/etc/ld.so.cache", O_RDONLY) = 3
open("/usr/lib/libncursesw.so.5", O_RDONLY) = 3
open("/usr/lib/libasound.so.2", O_RDONLY) = 3
open("/lib/libm.so.6", O_RDONLY) = 3
open("/lib/libdl.so.2", O_RDONLY) = 3
open("/lib/libpthread.so.0", O_RDONLY) = 3
open("/lib/libc.so.6", O_RDONLY) = 3
open("/usr/share/alsa/alsa.conf", O_RDONLY) = 3
open("/dev/snd/controlC0", O_RDONLY) = -1 ENODEV (No such device)
open("/dev/aloadC0", O_RDONLY) = -1 ENODEV (No such device)
alsamixer: function snd_ctl_open failed for default: No such device
Process 28188 detached
However, /dev/snd/controlC0 exists, even though the output of the above would lead me to believe differently.
What else is weird is, mplayer and xmms can play sounds just fine, but Firefox and aplay cannot.
More information about my setup is available from the output of an ALSA info script, here: http://pastebin.ca/591136 and http://pastebin.ca/590970
Any idea what's going on? This is very strange. Thanks.

Silly question, installed the drivers for the z?

Trying to get my sound card to work with ArchLinux

Okay, let me tell you my problem. I'm still somewhat of a noob when it comes to linux so don't be hard on me . And, yes that's half of my problem, anyways I've got a sound card called the Soundblaster X-FI USB and I've been trying it to get it to work with the alsaconf command which hasn't worked of course Let me point out that whenever I use my backup flashdrive with PuppyLinux it the Alsaconf inside of it see's the card that I'm using and automatically sets it up.. Plus whenever I type the ' cat /proc/asound/cards ' command I get this..
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xefffc000 irq 21
1 [S51 ]: USB-Audio - SB X-Fi Surround 5.1
Creative Technology SB X-Fi Surround 5.1 at usb-0000:00:1d.2-2, full speed
*(The first one being my dead onboard audio)
So please help me out here I really want to have sound again and hey maybe I'll learn something new about linux!

there's some experimental driver that maybe makes it work with alsa, see here:
http://www.phoronix.com/scan.php?page=n … &px=Njc3NQ
My card is a USB which isn't compatible with the driver that they include. So no help there ;(. I've loaded Ubuntu recently and it has worked perfectly with my soundcard (Creative X-FI USB Surround 5.1) right out of the box. I personally think there has to be a way to get it to work in Archlinux since it worked in Ubuntu...
Although. I suppose I could just use Ubuntu but I'm more of a fan of Arch. So does anyone have any idea what Ubuntu used as in drivers wise to get my card to work in linux??
