bluetooth connectivity not stable on ubuntu 22.04

yt flag

I have a laptop Lenovo y9000p 2022. On the laptop, I can connect the Bluetooth devices, but the laptop cant stable output sound through the Bluetooth devices.

I have tried to clone the git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git, and replaced the intel folder, and reboot the laptop, and still not work.

Sorry for the late reply. The cmd shows: damon@Y9000P:~$ lspci -knn | grep Net -A3 00:14.3 Network controller [0280]: Intel Corporation Alder Lake-P PCH CNVi WiFi [8086:51f0] (rev 01) Subsystem: Intel Corporation Device [8086:0094] Kernel driver in use: iwlwifi Kernel modules: iwlwifi

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
