I'm working on a computer with a 5.1 sound card and am running Debian Sid.

$ dpkg -l pulseaudio
ii  pulseaudio  0.9.21-1.2  PulseAudio sound server

$ lspci -vvv | grep audio
02:09.0 Multimedia audio controller: Cirrus Logic CS 4614/22/24/30
[CrystalClear SoundFusion Audio Accelerator] (rev 01)

I've tweaked /etc/pulse/daemon.conf as follows:

; default-sample-channels = 2
 default-sample-channels = 6
; default-channel-map = front-left,front-right
 default-channel-map =

and restarted pulse.

However, I see that my channels are still at two:

$ pactl list
Sink #0
        State: SUSPENDED
        Name: alsa_output.pci-0000_02_09.0.analog-stereo
        Description: CS 4614/22/24/30 [CrystalClear SoundFusion Audio
Accelerator] Analog Stereo
        Driver: module-alsa-card.c
        Sample Specification: s16le 2ch 44100Hz
        Channel Map: front-left,front-right

Do I need to configure alsa for 5.1 sound as well as PA?

Thanks for any advice,
