I've been using a Sound Blaster Z for 2 years (from kernel 5.14) and never experienced the issue you mentioned, but since the last kernel update (6.1.12 I think), I completely lost surround sound. The issue surfaces in a similar way as you, L+R only, no matter the settings in alsamixer or speaker-test. This is what alsa-info.sh dmesg section looks like for me: [ 6.256560] snd_hda_codec_ca0132 hdaudioC3D1: autoconfig for Sound Blaster Z: line_outs=3 (0xb/0x11/0x10/0x0/0x0) type:line [ 6.256568] snd_hda_codec_ca0132 hdaudioC3D1: speaker_outs=0 (0x0/0x0/0x0/0x0/0x0) [ 6.256571] snd_hda_codec_ca0132 hdaudioC3D1: hp_outs=1 (0xf/0x0/0x0/0x0/0x0) [ 6.256573] snd_hda_codec_ca0132 hdaudioC3D1: mono: mono_out=0x0 [ 6.256574] snd_hda_codec_ca0132 hdaudioC3D1: dig-out=0xc/0xd [ 6.256576] snd_hda_codec_ca0132 hdaudioC3D1: inputs: [ 6.256578] snd_hda_codec_ca0132 hdaudioC3D1: Mic=0x12 [ 6.256580] snd_hda_codec_ca0132 hdaudioC3D1: Line=0x13 [ 6.256581] snd_hda_codec_ca0132 hdaudioC3D1: dig-in=0xe [ 6.795248] snd_hda_codec_ca0132 hdaudioC3D1: ca0132 DSP downloaded and running [ 7.202572] input: HDA Creative Mic as /devices/pci0000:80/0000:80:00.0/0000:81:00.0/sound/card3/input32 [ 7.264138] input: HDA Creative Line Out Front as /devices/pci0000:80/0000:80:00.0/0000:81:00.0/sound/card3/input33 [ 7.277203] input: HDA Creative Line Out Surround as /devices/pci0000:80/0000:80:00.0/0000:81:00.0/sound/card3/input34 [ 7.277332] input: HDA Creative Line Out CLFE as /devices/pci0000:80/0000:80:00.0/0000:81:00.0/sound/card3/input35 [ 7.277536] input: HDA Creative Front Headphone as /devices/pci0000:80/0000:80:00.0/0000:81:00.0/sound/card3/input36 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1261211 Title: No multichannel support on Creative CA0132 Status in ALSA driver: Confirmed Status in alsa-driver package in Ubuntu: Won't Fix Bug description: Multichannel sound is not working on my Creative CA0132 sound card.
