 Posted: Thu Dec 30, 2004 6:29 pm Post subject: Second soundcard and ALSA [SOLVEDish] |
 |
|
I have a laptop and recently decided to purchase a SoundBlaster MP3+ USB thingy so that I could have the sound play over my home theatre when the computer is docked. I know the USB sound card works under linux since I tested it out in Knoppix and worked fine.
The laptops on board sound works fine under alsa. Alsa and intel8x0 both compiled as modules. When I try to play sound through the USB card however, I get this:

| Can you turn the primary soundcard off in the BIOS? Just to check if the acual problem is the card itself or the fact that there are two cards. |

I do not think I can, the BIOS on this computer is very non-tinker-friendly.. I did however remove the entry for the onboard card from /etc/modules.d/alsa, and switched the usb-audio entry to snd-card-0, unloaded all the sound drivers and restarted alsasound.
At that point the intel8x0 drivers were not loaded, and /proc/asound/cards showed only the Sound Blaster USB. In this situation I continued to get the same error message.
This is very frustrating since, like I said, I was able to get the card to work under Knoppix.. I guess I need to spend more time in there trying to determine what exactly the difference is. |

This still doesn't make much since to me, since as I had said before it worked under Knoppix as it was, but...
I thought I'd take a break from my desk, undocked the laptop and sat by the TV.. when I plugged the sound card into the laptop, suddenly it worked! Not knowing what I did I brought it back up, docked it, plugged everything back in the way it was, and once again it did not work. After some experimentation I discovered that it only worked when plugged into one of the USB ports on the laptop itself. It could not be plugged in to either the docking station ports, nor a hub (externally powered or not)...
So in conclusion, I still don't know whats wrong...someday would like to find out, but right now it works and I just don't care anymore... |

Are you running hotplug?
Try tailing dmesg/grepping it for the driver of the USB thing. |

| I have the same problem. I just noticed that you are right. It only works if its directly plugged into the notebook. Not very elegant but works. |

same problem, same solution
is there any reason this shouldn't work when plugged into an external hub? eg, is this a proper alsa bug, or a 'feature'?
