https://bugzilla.kernel.org/show_bug.cgi?id=56791 Summary: Extreme stutter streaming A2DP audio to IMC device 13d3:3315 Product: Drivers Version: 2.5 Kernel Version: 3.2.0-39-generic Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: blocking Priority: P1 Component: Bluetooth AssignedTo: linux-bluetooth@xxxxxxxxxxxxxxx ReportedBy: davidmcnabnz@xxxxxxxxx Regression: No Symptom noticed on EeePC 1015BX running Linux Mint 13 LXDE (32bit), which has an on-board IMC Networks bluetooth adapter, which is electrically wired as a USB device, with ID 13d3:3315. Using bluez bluetooth stack, pulseaudio audio framework and blueman management utility, I am able to pair the device and set up the A2DP connection. However, streaming of audio is very choppy, with dropouts of several hundred milliseconds happening dozens of times a minute. I tried plugging in a Cambridge Silicon Radio-based USB bluetooth dongle, with the ID 0a12:0001, and A2DP audio streaming works 100% perfectly. Zero dropouts. The bluetooth peripheral is Logitech Wireless Headset (no model number). Please note that according to Blueman, the internal IMC device reports the same signal quality and connection quality as the Cambridge Silicon Radio dongle, so I would tend to rule out the RF transceiver and internal antenna as a possible cause. Apologies if this bug has already been rectified in a later kernel. I did search the tracker but found no references to IMC Networks, or the device ID. I would be very grateful to see this issue resolved. A major reason for having a netbook computer is its convenience and portability, and needing to plug in an external dongle, vulnerable to bumps and damage, takes away from this. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
