After some thought. I think the Bug needs to be redefined. I believe the original problem is in the hardware and not a software bug. That is the ath9k hardware as used by some computers is at fault and the wireless can not be used at the same time as lower latency audio. However, what is a bug is that the transceiver can be turned off using either network- manager or in many cases a hardware switch but this rather than making things better makes it worse.
If the system is started with network-manager disabled by renaming it's upstart file, there is no problem with audio even though the eth9k module is loaded. It is in an off state. Once the driver has been used and the hardware it controls is turned off, then ath9k should go back to sleep untill network-manager (other other program) wakes it up. ath9k needs to be fixed so it gets reset when the hardware is turned off. ** Summary changed: - ath9k locks kernel in 10 ms, causing e g audio dropout + ath9k locks kernel in 10 ms, causing e g audio dropout, ath9k doesn't reset when wireless is turned off. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/671240 Title: ath9k locks kernel in 10 ms, causing e g audio dropout, ath9k doesn't reset when wireless is turned off.
