[SOLVED] Bluetooth headphones get disconnected

Sujay1844 · 2021-04-08 00:23:35

I'm a newbie here (Installed Arch 2 days back. before that I used Manjaro). My bluetooth headphones gets disconnected suddenly. They stop playing audio for 10 sec, then get disconnected (I know it because sound plays out of the built-in speakers) and then get connected back automatically. This happens for Spotify, Microsoft Teams, MPV player. I tried to log the time when this happens but it's random.

# DID profile support. The values are separated by ":" and assigner, VID, PID
# and version.
# Possible vendor id source values: bluetooth, usb (default) or false (disabled)
#DeviceID = bluetooth:1234:5678:abcd

# Do reverse service discovery for previously unknown devices that connect to
# us. For BR/EDR this option is really only needed for qualification since the
# BITE tester doesn't like us doing reverse SDP for some test cases, for LE
# this disables the GATT client functionally so it can be used in system which
# can only operate as peripheral.

#MultiProfile = off

# Permanently enables the Fast Connectable setting for adapters that
# support it. When enabled other devices can connect faster to us,
# however the tradeoff is increased power consumptions. This feature

# Enables use of private address.
# Possible values: "off", "device", "network"

# Enables the device to issue an SDP request to update known services when
# profile is connected. Defaults to true.
#RefreshDiscovery = true

[BR]
# The following values are used to load default adapter parameters for BR/EDR.
# BlueZ loads the values into the kernel before the adapter is powered if the

# value will vary based on the kernel version and thus aren't provided here.
# The Bluetooth Core Specification should be consulted for the meaning and valid
# domain of each of these values.

[Policy]
#
# The ReconnectUUIDs defines the set of remote services that should try
# to be reconnected to in case of a link loss (link supervision
# timeout). The policy plugin should contain a sane set of values by
# default, but this list can be overridden here. By setting the list to
# empty the reconnection feature gets disabled.

# ReconnectAttempts define the number of attempts to reconnect after a link
# lost. Setting the value to 0 disables reconnecting feature.
#ReconnectAttempts=7

# ReconnectIntervals define the set of intervals in seconds to use in between
# attempts.
# If the number of attempts defined in ReconnectAttempts is bigger than the
# set of intervals the last interval is repeated until the last attempt.
#ReconnectIntervals=1,2,4,8,16,32,64

# AutoEnable defines option to enable all controllers when they are found.
# This includes adapters present on start as well as adapters that are plugged
# in later on. Defaults to 'false'.
#AutoEnable=false

# Audio devices that were disconnected due to suspend will be reconnected on
# resume. ResumeDelay determines the delay between when the controller
# resumes from suspend and a connection attempt is made. A longer delay is
# better for better co-existence with Wi-Fi.
# The value is in seconds.
# Default: 2
#ResumeDelay = 2

-> Bluetooth thread

Sounds like what´s reported in that thread. There´s some posts linking to what chipsets are affected.

Thanks. I downgraded

. It works fine.
