Very robotic and slightly slower than usual Status in The Linux Kernel: Confirmed Status in “linux” package in Ubuntu: Confirmed Bug description: Using the POD Studio UX2 and Ubuntu 13.04 with the later releases of the 3.8.0 linux kernel the audio sounds very robotic and is slightly slower than usual. If I remember correctly I was able to get the sound back to normal on a slightly earlier release of the 3.8.0 linux kernel, but i have reinstalled Ubuntu 13.04 since. The problem occurs with everything that is played, so it is not an issue with particular applications. My speakers are connected in stereo through the 2 analogue outs at the back of the device. I have never had this issue on previous releases of Ubuntu. Playing music with this issue makes the music difficult and overall pointless to listen to. I have even disabled my onboard sound to see if that may be the problem, but the issue still occurs. I believe it is a sound driver issue relating to the later kernel releases. I hope the issue can be resolved. Thank you. UPDATE: The issue also affects the Line6 Toneport GX according to a user that commented on my youtube video, also another user has commented on my video saying that they have the same issue with their UX2 device. This shows that the issue is more than my own. It also shows that it affects other Line6 devices. I really hope this issue can be resolved before the next major kernel release at the least. Thank you again.
