Alsa and AC97

chastulsa · 07-27-2007, 09:57 PM

Ok how do I change my sound card? it detected stupid modem as sound card and now I lost sound. I reran alsaconf and reinstalled newest drivers alsaconf detects my ac97 card but alamixer shows conexant?

Card: Conexant CX8801 ││ Chip: CX88 ││ View: [Playback] Capture All

i have intel ac97 how to I change the device?

Bruce Hill · 07-28-2007, 12:27 AM

I don't think that AC'97 is actually what the sound chip is. Please post the output of: "/sbin/lspci | grep -i audio" to get your true audio chipset.

chastulsa · 07-28-2007, 08:56 AM

Code:

bash: /sbin/lspci: No such file or directory

alsa conf finds

Code:

intel8x0                         Intel Corporation 82801EB/ER AC97

thanks for the help!

If your Linux distribution does not have "/sbin/lspci" you need to get another one. That is standard for every Linux, afaik. So what other advice is going to work for that box?

As root issue "modprobe snd-intel8x0" and that should get your sound chip inserted in the kernel. Then issue "lsmod" and pray you have a listing of your modules. If you do, post the output here ... using code tags as you've done before.

To check your sound, if you have some intel8x0 modules, issue "speaker-test -Dplug:front -c2 -t wav" in a terminal. If that doesn't work, issue "cat /dev/urandom > /dev/dsp" and be ready to quickly hit "Ctrl+C" to stop the output.

If 'alsaconf' detects the right card you are halfway through - with mine that was the hardest part. Just in case check to see if the right card is in '/etc/modprobe.d/sound' and then modprobe the module - it should be snd-hda-intel. Then check to see if the sound works properly. If it does do a 'alsactl store' just in case.

Post back if you are still having problems.

Have fun!

I still refuse to believe that "lspci" is not installed on a Debian system. That one command will show us which sound card chipset you need to use. Issue it as root, just "lspci" without the " marks and post the output.

When you find the correct sound module to use, you're going to need to remove (rmmod) the other ones you have there.

You got a serious looking problem here:

also I think the conexant is my "ATI HDTV WONDER" after looking at the above.

Bruce Hill · 07-28-2007, 09:27 PM

So Debian does have lspci installed.

Now look at what you've got in that box:

Code:

00:1f.5 Multimedia audio controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) AC'97 Audio

That's your audio controller.

This other entry:

Code:

02:03.0 Multimedia video controller: Conexant CX23880/1/2/3 PCI Video and Audio Decoder (rev 05)
02:03.1 Multimedia controller: Conexant CX23880/1/2/3 PCI Video and Audio Decoder [Audio Port] (rev 05)
02:03.2 Multimedia controller: Conexant CX23880/1/2/3 PCI Video and Audio Decoder [MPEG Port] (rev 05)

is a video controller. I would guess a PCI video capture card?

I don't use Debian, nor do I have any Intel chipsets. But Krassi, who does, wrote:

Quote:

check to see if the right card is in '/etc/modprobe.d/sound' and then modprobe the module - it should be snd-hda-intel.

So what you need to do, while root in that terminal, is issue "cat /etc/modprobe.d/sound" and see what's in there. You could post that output and Krassi will help you from there. If you see "snd-hda-intel" and he's right, issue as root "modprobe snd-hda-intel" and then it should show up in "lsmod" output, and you should have sound.

I asked you to post "df -hT" because previously you posted:

Quote:

debian:/home/chas# cat /dev/urandom > /dev/dsp
cat: write error: No space left on device

I don't know how your system is setup like that, but this looks terribly weird to me:

Quote:

tmpfs tmpfs 1015M 0 1015M 0% /lib/init/rw
udev tmpfs 10M 10M 0 100% /dev
tmpfs tmpfs 1015M 0 1015M 0% /dev/shm

Such as, why is udev mounted on a tmpfs? The mount point is /dev and it is full. Strange to me ...

krassi · 07-29-2007, 02:08 PM

As Bruce said that Conexant thingie looks like a A/V capture card. If you don't use it you can just do (everything following is as su)

Code:

modprobe -r cx88_alsa

Then try running alsamixer again. It should only see the Intel card. If it does do a 'alsactl store' and restart alsa:
# /etc/init.d/alsasound restart
Now you can test the sound. If it still sees the modem or the A/V capture thingie post me an output from
# cat /proc/asound/cards
If the Conexant (cx88) is the first card in the list add 'options snd-cx88-alsa dsp_map=-2' at the end of '/etc/modprobe.d/alsa-base' and reload the alsa modules by '/etc/init.d/alsa reload' or you may just need to restart alsasound.

Here is probably everything you need to know to troubleshoot sound in Debian: http://www.debianhelp.co.uk/sound.htm

If you are still having problems post the output from (as a normal user do):
1. $ cat /proc/asound/cards
2. $ cat ~/.asoundrc (if you have it)
3. $ cat /etc/asound.conf (if you have it)

1. $ cat /proc/asound/cards

Code:

                      Intel ICH5 with ALC655 at 0xeffffa00, irq 209

2. $ cat ~/.asoundrc (if you have it)

Code:

debian:/home/chas# at ~/.asoundrc
syntax error. Last token seen: /
Garbled time

3. $ cat /etc/asound.conf (if you have it)

Code:

debian:/home/chas# cat /etc/asound.conf
cat: /etc/asound.conf: No such file or directory

so sound mixer shows the right card i have sound on some appz but not all?

krassi · 07-29-2007, 10:35 PM

Everything looks right - I don't want to say terribly right. Try this:
1. (as root) alsactl store
2. Restart the PC
3. After you boot back in run alsamixer again. Everything should be fine. Test with a few programs like juk, amarok, so on. If you find that some of them recognize the right card and others don't take note of which do and don't and post us back. We'll figure it out from there.

HF!
Krassi

PS: Don't despair we'll figure it out.
