If anyone has any older package files after v120.0.6099.216, I'd be interested in finding the last version that worked. |
I've been successfully using the Volt 176 USB interface with FreeBSD-CURRENT, chromium, webrtc, and sndio for a while. Some time after v120.0.6099.216 I my microphone input becomes distorted. People on the other end say I sound like a robot. Refreshing the tab fixes the problem. I haven't been able to identify the last version that works because I don't have any historical packages. This problem happens 100% of the time. It begins at unpredictable times -- it could be almost immediately or it could be 10 minutes into a chat. This is the case with google meet, google voice, zoom, and microsoft teams. My microphone works fine in other applications like firefox, OBS studio, and audacity. hw.audio sysctls: $ sysctl hw.audio sysctl: unknown oid 'hw.audio' [ayan@kiwi ~]$ sysctl -a | grep hw.audio [ayan@kiwi ~]$ sysctl -a | grep hw.sound [ayan@kiwi ~]$ sysctl -a | grep hw.snd hw.snd.maxautovchans: 16 hw.snd.default_unit: 4 hw.snd.version: 2009061500/amd64 hw.snd.default_auto: 1 hw.snd.verbose: 4 hw.snd.vpc_mixer_bypass: 1 hw.snd.feeder_rate_quality: 1 hw.snd.feeder_rate_round: 25 hw.snd.feeder_rate_max: 2016000 hw.snd.feeder_rate_min: 1 hw.snd.feeder_rate_polyphase_max: 183040 hw.snd.feeder_rate_presets: 100:8:0.85 100:36:0.92 100:164:0.97 hw.snd.feeder_eq_exact_rate: 0 hw.snd.feeder_eq_presets: PEQ:16000,0.2500,62,0.2500:-9,9,1.0:44100,48000,88200,96000,176400,192000 hw.snd.basename_clone: 1 hw.snd.compat_linux_mmap: 0 hw.snd.syncdelay: -1 hw.snd.usefrags: 0 hw.snd.vpc_reset: 0 hw.snd.vpc_0db: 45 hw.snd.vpc_autoreset: 1 hw.snd.timeout: 5 hw.snd.latency_profile: 1 hw.snd.latency: 2 hw.snd.report_soft_matrix: 1 hw.snd.report_soft_formats: 1 uaudio sysctls: $ sysctl -a | grep uaudio <118>Autoloading module: snd_uaudio uaudio0 numa-domain 0 on uhub0 uaudio0: <Universal Audio Volt 176, class 239/2, rev 2.00/1.00, addr 5> on usbus0 uaudio0: Play[0]: 192000 Hz, 2 ch, 32-bit S-LE PCM format, 2x4ms buffer.
