    SB Live card permanently mute


    I'm using an SB live PCI card on a AMDx2 system with Mandriva 2008.1.

    It was working perfectly for years with every single distro I had. A few weeks ago I bought an external audio device from Behringer, which also worked well (alongside the SBLive). The only problem with that was that it didn't support hardware mixing so I decided to go back to my sblive. Also, during that time period, I had a motherboard failure, so I'm not sure if that has anything to do with it. Here's what I know...

    1. /dev/dsp and /dev/mixer devices are present
    2. Audacity detects the card under ALSA
    3. All mixer settings are maxed out and not muted
    4. The card was tested today in an XP box and is working
    5. No programs make any complaint about the card
    6. I can run a radio on the line in and manipulate the volume via aumix
    7. ALSA thinks the USB device is still there even though I booted without it.

    Thanks

    Welcome to the forums!

    Not sure what's happening here, but have you tried the following commands from the command line to see if reconfiguring will get you past this issue?

    Code:
    alsaconf
    
    alsamixer
    
    alsactl store

    Thanks for replying. I ran all three commands. It detected the card properly and set the mixer. I heard some pops from the speaker as the volume was adjusted, but when I play something, there's only silence.

    All the mixer sliders are all the way up and unmuted. I can't figure this out.

    It insists that I still have a USB audio device connected to it when I do not.

    Also, I found this in dmesg:

    ACPI: PCI interrupt for device 0000:01:09.0 disabled
    ACPI: PCI Interrupt 0000:01:09.0[A] -> Link [LNKB] -> GSI 19 (level, low) -> IRQ 19
    1:09:0 is my SB Live. The card definitely needs an IRQ to fill its buffer. That would explain why it's quiet. What can I do to prevent this?
