Done so. It didn't help. It's mightily curious why that one device is |
27 |
different from the others. It's not so under udev. |

Anyhow I found the problem. It was pulseaudio. I rebuilt it with its |
30 |
udev use flag taken out. This didn't help. |

Then I rebuilt aqualung without the pulseaudio flag, and now things work. |

As I type, I am listening to Mahler's second symphony, played by the |
35 |
Bamberger Symphoniker conducted by Jonathan Nott. I can recomment Mahler |
36 |
for when things aren't going quite according to plan, and this recording |
37 |
in particular. |
