This bug is specific to arale, krillin, and most likely vegatta ( although as I don't have once, I haven't been able to test ). It's related to the fact that on devices using MTK's Wi-Fi driver, we're forced to use hybris for power control of the Wi-Fi radios. This leverages the Android HAL functions wifi_load/unload_driver(). On systems configured without kernel modules, this results in a driver command to start/stop Wi-Fi ( this is accomplished by writing the string "0" or "1" to the character device ( /dev/wmtWiFi ).
I just checked mako ( rc-proposed, #222 ) and no stuttering occurs when Wi-Fi is enabled or disabled. Also re-checked arale ( rc-proposed, #88 ) and krillin ( rc-proposed, #104 ) and both still skip/stutter when Wi-Fi is toggled. Bug #1487529 reported for arale. ** Summary changed: - Toggling wifi on/off causes media playback to hiccup + [arale/krillin] Toggling wifi on/off causes media playback to hiccup -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1388201 Title: [arale/krillin] Toggling wifi on/off causes media playback to hiccup Status in Canonical System Image: Confirmed Status in Network Menu: Invalid Status in network-manager package in Ubuntu: Incomplete Bug description: 1.
