The error is correct in that you are missing a required parameter. That command should be in the format of $ asoundconf set-default-card soundcard-name i.e. $ asoundconf set-default-card V8237 or $ asoundconf set-default-card AudioPCI, which ever card you want to set as default.
As far as which card is which, I would suspect V8237 is an onboard VIA Chipset on your motherboard and the latter a 'PCI add-on card' You can also install the GUI Tool for the default sound card, asoundconfgui. Not exactly sure on the name... -- gutsy upgrade tells me to run a command which fails https://bugs.launchpad.net/bugs/136750 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
