USB sound card inserted
Open xterm become root.
tazpkg get-install usbutils,libusb, and linux-sound

root@slitaz: tazhw detect-usb

If slitaz includes the sound module for the chip it will load.

Thanks I installed all those packages,
I ran tazhw detect-usb, and it now shows with lusb:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 002: ID 0c76:1607 JMTek, LLC.
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

However when I use flash player on youtube, the sound is still coming from the Intel onboard sound. When I run alsamixer, I only see the options listed below, so I can't select USB audio.


This is what is in /proc/asound/cards:

0 [I82801DBICH4 ]: ICH4 - Intel 82801DB-ICH4
Intel 82801DB-ICH4 with AD1981B at irq 11
1 [Modem ]: ICH-MODEM - Intel 82801DB-ICH4 Modem
Intel 82801DB-ICH4 Modem at irq 11

root@slitaz: soundconf

USB audio is recognized in list window choose it.
If the USB sound still doesn't work:
Slitaz may have limitation on the audio install script that would prevent more than one sound device from being configured at a time.
Find out if the USB sound will work by itself.
Turn Intel motherboard sound off in bios so it doesn't interfere with USB sound install.
Rerun tazhw detect-usb is there any reply about these modules loaded:
snd-usb-caiaq.ko.gz
snd-usb-audio.ko.gz
snd-usb-lib.ko.gz
snd-usb-us122l.ko.gz
snd-usb-usx2y.ko.gz

root@slitaz: soundconf

If you still have no sound what is output:

root@slitaz: lsmod | grep snd_usb*

There is no output, it just returns to the cursor. I also have jack-audio-connection-kit installed. I don't now if that makes a difference.

Sad to say your USB sound is not going to work with Slitaz :(

The BIOS doesn't have an audio setting for this laptop, so I can't turn it off. It does see the sound on the modem and lists it as a 2nd device. When I run lsmod | grep snd_usb* there is no reply. When I run tazhw detect-usb it says:

Detected USB devices Kernel modules

Then I ran lsusb

If I do this, the LED on the device pulses, but no sound:

Oh well, thanks for the help. I learned a bit about alsa anyway. If I need to make a phone call with Skype, I can just boot to Windows. The onboard sound is fine for everything else.

Open alsamixer hit F6 and see if the USB sound device is listed.
Glad to help.

I got usb speakers working last night with audacious which allows you to choose a device. Skype gives you also that option.

USB device not seen in alsamixer or in Skype sound options. I'm not going to bother with it any more, though it was an interesting exercise. I found I can plug the headphone part of the headset in and use the built in microphone if I have to. It is just the microphone jack that is broken, or the connection between the jack and the system board.

I really like this distro, it runs great on this IBM laptop. The window manager and file manager are a real treat compared to Puppy Linux.
