I’m using latest Manjaro KDE stable and telegram-desktop from community repository. When I’m trying to play any audio file it plays in mono instead in stereo.
Specs if its important:
Z270 PC MATE ; Pentium G4560 ; Intel HD Graphics 610 ; 8GB RAM ; NVME 250GB
linux57.17-2 ; xorg-session
Could you paste the output of:
pacmd list-sink-inputs
when running telegram audio file.
1 sink input(s) available.
index: 122
driver: <protocol-native.c>
flags: START_CORKED
state: RUNNING
sink: 0 <alsa_output.pci-0000_00_1f.3.analog-stereo>
volume: front-left: 65536 / 100% / 0,00 dB, front-right: 65536 / 100% / 0,00 dB
balance 0,00
muted: no
current latency: 30,83 ms
requested latency: 20,00 ms
sample spec: float32le 2ch 48000Hz
channel map: front-left,front-right
Stereo
resample method: copy
module: 12
client: 129
properties:
media.name = “Playback Stream”
application.name = “telegram-desktop”
native-protocol.peer = “UNIX socket client”
native-protocol.version = “33”
application.icon_name = “telegram”
application.process.id = “1048”
application.process.user = “antoni”
application.process.host = “antoni-ms7a72”
application.process.binary = “telegram-desktop”
application.language = “en_US.UTF-8”
window.x11.display = “:0”
application.process.machine_id = “fb30567e6b694daf82a964ff63116dc2”
application.process.session_id = “1”
module-stream-restore.id = “sink-input-by-application-name:telegram-desktop”
So its not the problem of pulseaudio or alsa:
I would rather say the audio playback of telegram is mono or the audio file is mono (gets converted). I would rather post an issue here: Issues · telegramdesktop/tdesktop · GitHub (if i were you)
