Hi, I just got a Dell Slim (USB) Soundbar SB522A and it seems to not be functionnal on OpenBSD 7.6 (and latest snapshot available tonight). I have tested in on Windows 11 and FreeBSD 14.1 and it works as expected.
Here's what dmesg says when I plug it in: umodem0 at uhub1 port 7 configuration 1 interface 0 "DELL DELL Slim Soundbar SB522A" rev 2.00/0.00 addr 5 umodem0: data interface 1, has no CM over data, has no break umodem0: status change notification available ucom0 at umodem0: usb1.0.00007.1 uaudio0 at uhub1 port 7 configuration 1 interface 3 "DELL DELL Slim Soundbar SB522A" rev 2.00/0.00 addr 5 uaudio0: class v1, full-speed, sync, channels: 2 play, 2 rec, 4 ctls audio1 at uaudio0 uhidev0 at uhub1 port 7 configuration 1 interface 5 "DELL DELL Slim Soundbar SB522A" rev 2.00/0.00 addr 5 uhidev0: iclass 3/0, 185 report ids ucc0 at uhidev0 reportid 1: 3 usages, 3 keys, enum wskbd1 at ucc0 mux 1 wskbd1: connecting to wsdisplay0 uhid0 at uhidev0 reportid 5: input=1, output=1, feature=0 uhid1 at uhidev0 reportid 154: input=0, output=0, feature=63 uhid2 at uhidev0 reportid 155: input=2, output=0, feature=0 uhid3 at uhidev0 reportid 184: input=63, output=0, feature=0 uhid4 at uhidev0 reportid 185: input=0, output=63, feature=0 Reading the Multimedia FAQ, I did: $ doas rcctl set sndiod flags -f rsnd/0 -F rsnd/1 $ doas rcctl restart sndiod Then using mpv to play a video, it freezes a few seconds before starting, the sound gets out of the laptop speaker (and not the USB soundbar). dmesg adds: uaudio0: can't reset interface uaudio0: can't reset interface sndioctl also takes a few seconds to output things: $ sndioctl -v output.level=1.000 server.device=1 app/mpv0.level=1.000 $ sndioctl -d 013:output.level=0..127 (127) 011:server.device=0(azalia0) 012:server.device=1 001:mpv0.level=0..127 (127) Here's a few more outputs: $ doas mixerctl -v inputs.dac-2:3=128,128 inputs.dac-0:1=128,128 record.adc-0:1_mute=off [ off on ] record.adc-0:1=192,192 record.adc-2:3_mute=off [ off on ] record.adc-2:3=192,192 outputs.spkr_source=dac-2:3 [ dac-2:3 ] outputs.spkr_mute=off [ off on ] outputs.spkr_eapd=on [ off on ] outputs.spkr2_source=dac-2:3 [ dac-2:3 dac-0:1 adc-0:1 ] outputs.spkr2_mute=off [ off on ] outputs.spkr2_boost=off [ off on ] inputs.mic=170,170 outputs.mic_dir=input-vr80 [ none input input-vr0 input-vr50 input-vr80 input-vr100 ] outputs.hp_source=dac-0:1 [ dac-2:3 dac-0:1 ] outputs.hp_mute=off [ off on ] outputs.hp_boost=off [ off on ] outputs.hp_eapd=on [ off on ] record.adc-2:3_source=mic { mic } record.adc-0:1_source=mic { mic } outputs.mic_sense=unplugged [ unplugged plugged ] outputs.hp_sense=unplugged [ unplugged plugged ] outputs.spkr_muters=hp { hp } outputs.master=128,128 outputs.master.mute=off [ off on ] outputs.master.slaves=dac-2:3,dac-0:1,spkr,spkr2,hp { dac-2:3 dac-0:1 spkr spkr2 hp } record.volume=192,192 record.volume.mute=off [ off on ] record.volume.slaves=adc-0:1,adc-2:3 { adc-0:1 adc-2:3 mic } record.enable=sysctl [ off on sysctl ] $ doas usbdevs Controller /dev/usb0: addr 01: 8086:0000 Intel, xHCI root hub Controller /dev/usb1: addr 01: 8086:0000 Intel, xHCI root hub addr 02: 06cb:00fc Synaptics, product 0x00fc addr 03: 174f:1813 , Integrated Camera addr 04: 8087:0033 Intel, Bluetooth addr 05: 413c:8204 DELL, DELL Slim Soundbar SB522A $ doas usbdevs -v -a 05 addr 05: 413c:8204 DELL, DELL Slim Soundbar SB522A full speed, power 500 mA, config 1, rev 0.00, iSerial 0 driver: umodem0 driver: uaudio0 driver: uhidev0 Am I missing something?
