I'm happy this is pretty much solve. With the pulseaudio-modules-bt from comment 27 [2], I've experienced far less audio lag overall. Every now and again I get a small glitch that delays it 10ms or so, but it's so much better now I'm happy to close this and mark it as non-issue. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1810636 Title: Suspect QCA6174 btcoex | Ubuntu 18 Bluetooth Audio Skip/Stutter/Delay WiFi bandwidth conflict Dell XPS 9570 [Pending PulseAudio testing] Status in linux package in Ubuntu: Confirmed Bug description: I'm running Linux 4.20.0-042000-generic #201812232030 x64 on a Dell XPS 9570 with QCA6174 chipset, and have had the problem with Bluetooth audio choppiness ever since I have owned this laptop. This problem has persisted for me with previous kernels. If I disable wifi and use media on machine locally, the problem doesn't occur. Note: I've reverted back v4.18.0-13-generic and reproduced the problem for the apport-collect report. It started with Ubuntu 18.04 and continues with 18.10. It's particularly noticeable when the when saturating the WLAN connection with throughput, i.e. copying a large file sequentially across from a samba share, but also streaming video online results in the audio progressively delaying over-time.

It might be worth saying, however, without the pulseaudio-modules-bt in [2] in comment #27, the throughput of the WLAN was not affected when playing sound via the A2DP sync and I was seeing abotu 18 MB/s. Maybe I'm a bit premature in saying it's solely a pulseaudio-modules-bt issue.

[Kernel-packages] [Bug 1810636] Re: QCA6174 doesn't utilise btcoex - Ubuntu 18 Bluetooth Audio Skip/Stutter/Delay WiFi bandwidth conflict Dell XPS 9570
Ok, I'm pretty sure this is a pulseaudio issue now and I'm going to close. I reverted back to linux-firmware 1.176, and I had also used undervolt [1] to help reduce thermal load on the Core i9 Dell XPS 15 which has suffered from thermal shutdown under high load. I disabled undervolt service from running and ensured everything was back to normal values - the stuttering improved, but was still present. I then focused on the difference between my Mi8 and my Ubuntu 18.10 installation. The Mi8 is running a LinesageOS ROM that supports LDAC/Apt-X codecs. I noticed with the regular AD2P codec in Ubuntu that I was getting some noise included in the Bluetooth audio encoding, and it sounded much cleaner via the Mi8 connection. I then found pulseaudio- modules-bt repo on github [2] that includes [3] a Ubuntu 18.04|18.10 repo that enabled LDAC/Apt-X codecs, LDAC is supported by the Sony bluetooth speaker. After installing and rebooting the machine, I confirmed that the codec was correctly initialised in the a2dp sync: berg@bxps:~$ pactl list sinks | grep -e bluez -e a2dp_codec Name: bluez_sink.E0_37_BF_09_F9_8B.a2dp_sink Driver: module-bluez5-device.c Monitor Source: bluez_sink.E0_37_BF_09_F9_8B.a2dp_sink.monitor bluetooth.a2dp_codec = "LDAC" device.api = "bluez" bluez.path = "/org/bluez/hci0/dev_E0_37_BF_09_F9_8B" bluez.class = "0x240414" bluez.alias = "bshg" The sound is now perfect, and copying files across the network results in no stuttering. I think this proves that the btcoex support is working correctly and there is no issue specifically with the Qualcomm firmware. I notice if I pair the bluetooth speaker and play back audio my network throughput is limited to about 14-15 MB/s, when I turn of the speaker it improves to 17-18 MB/s. So the module is correctly allowing bluetooth to operate with priority. Resuming the undervolt [1] service, I notice no stuttering as well with the updated pulseaudio and pulseaudio-module-bt packages in [2]. I'm going to continue testing for a few days before closing this bug, but I'm pretty sure I've gotten to the bottom of this one. Thanks @kaihenfeng.

Here is a demo of the stuttering sound, you can hear it at around 11 seconds after I start a file copy over SMB. pulseaudio 1:12.2-0ubuntu4 Firmware seems less stable than that in linux-firmware 1.176. Getting strange delays with the WiFi in general. One thing I noticed was that it was better, but not perfect on my 2.4 GHz SSID/radio. During this time my throughput from my server is only about 2 MB/s. When I switch to 5 GHz SSID/radio, the throuhgput increases to around 20 MB/s. ** Attachment added: "Demo of stuttering while listening to" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1810636/+attachment/5227363/+files/stutter-demo.zip -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1810636 Title: QCA6174 doesn't utilise btcoex - Ubuntu 18 Bluetooth Audio Skip/Stutter/Delay WiFi bandwidth conflict Dell XPS 9570 Status in linux package in Ubuntu: Confirmed Bug description: I'm running Linux 4.20.0-042000-generic #201812232030 x64 on a Dell XPS 9570 with QCA6174 chipset, and have had the problem with Bluetooth audio choppiness ever since I have owned this laptop.

Ok, I managed to get the latest firmware working. It still exhibits the same issue. I think I must of only rebooted last time instead of shutting down completely. I've tried the speaker sitting on top of the track-pad, about 50 cm away from the laptop - all to the same effect - the it's like it misses an audio packet, and rather than dropping the packet, it re-transmits again, buffering all subsequent packets for the stream. I would rather lose the packets completely in this case. The speaker is a Sony SRS-HG1. I can pair the speaker to my Xiaomi Mi8 phone and it negotiates LDAC codec for the Bluetooth audio sink. I can then run high load on the Mi8 WiFi and play a movie in FullHD over DLNA and it never skips a beat, there is a small delay as you'd expect with Bluetooth, but it's less than 100 ms and seems normal after a short while. I experienced this problem also in another location when I was house sitting recently - so different environment/access points etc. I think demonstrating the problem with the speaker and my phone without any problems puts me back on the firmware/driver troubleshooting path.

Just to confirm, I suspect the move to Kernel 4.3 rc6 has got the 5 GHz scanning working. For some reason the device just doesn't want to connect to 5 GHz. Not sure if I can make the adapter connect to explicitly connect to 5 GHz as the network is advertised on both frequency bands. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1509614 Title: Wireless BCM43602 802.11ac cannot connecto to 5 GHz networks - MacBook Pro 11,5 Status in linux package in Ubuntu: Incomplete Bug description: What I expect to happen: I expect to be able to scan 5 GHz channels and connect to them using the BCM43602 chipset in a MacBook Pro 11,5.

@penalvch TP-Link Archer C5_V1.20_150428 is the firmware on the access point. Other 5 GHz devices are connecting fine. I'm currently at work and we have an enterprise 802.11x setup with Cisco AIR-CAP3602I-N-K9 APs with the AIR-RM3000AC-Z-K9 AC modules. I am unsure what firmware revision is on the Cisco APs, they are centrally managed by WISM controllers. What is interesting at this point is that I can now see the networks advertised on the 5 GHz band, indicating that the scan for these networks is working. My android device is definitely connecting on 5 GHz correctly. The MacBook Pro 11,5 with the broadcom chipset only connects to the 2.4 GHz endpoints. ** Attachment added: "This contains dmesg output for 80211 entries and 5 GHz scan in Cisco enviornment" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1509614/+attachment/4506158/+files/cisco-ap-environment.log ** Summary changed: - Wireless BCM43602 802.11ac 5 GHz not scanable on linux-firmware 1.1.49 - MacBook Pro 11,5 + Wireless BCM43602 802.11ac cannot connecto to 5 GHz networks - MacBook Pro 11,5 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1509614 Title: Wireless BCM43602 802.11ac cannot connecto to 5 GHz networks - MacBook Pro 11,5 Status in linux package in Ubuntu: Incomplete Bug description: What I expect to happen: I expect to be able to scan 5 GHz channels and connect to them using the BCM43602 chipset in a MacBook Pro 11,5.
