Public bug reported: Hello,
I am using Ubuntu 19.10 with 5.1 surround speakers. I tried to configure 5.1 surround, but it still doesn't work. I also installed Pulse audio. Here is the info about my soundcard: # aplay -l **** Lista PLAYBACK de dispozitive **** placa 0: PCH [HDA Intel PCH], dispozitiv 0: ALC892 Analog [ALC892 Analog] subdispozitive: 0/1 Subdispozitiv #0: subdevice #0 placa 1: NVidia [HDA NVidia], dispozitiv 3: HDMI 0 [HDMI 0] subdispozitive: 1/1 Subdispozitiv #0: subdevice #0 placa 1: NVidia [HDA NVidia], dispozitiv 7: HDMI 1 [HDMI 1] subdispozitive: 1/1 Subdispozitiv #0: subdevice #0 placa 1: NVidia [HDA NVidia], dispozitiv 8: HDMI 2 [HDMI 2] subdispozitive: 1/1 Subdispozitiv #0: subdevice #0 placa 1: NVidia [HDA NVidia], dispozitiv 9: HDMI 3 [HDMI 3] subdispozitive: 1/1 Subdispozitiv #0: subdevice #0 See 'lscpi -v' output attached. $ speaker-test -c6 -l1 -twav speaker-test 1.1.9 Playback device is default Stream parameters are 48000Hz, S16_LE, 6 channels WAV file(s) Rate set to 48000Hz (requested 48000Hz) Buffer size range from 32 to 349525 Period size range from 10 to 116509 Using max buffer size 349524 Periods = 4 was set period_size = 87381 was set buffer_size = 349524 0 - Față stânga 4 - Centru 1 - Față dreapta 3 - Spate dreapta 2 - Spate stânga 5 - LFE Timp per Perioada = 8,733519 I tried the test below and instead of center speaker, right speaker plays two times and the subwoofer do not work at all.
