FreeBSd-12.1p10 Firefox-82.0.1. I have a system that has only basic VGA video on board and requires a separate video card for anything else. The card installed is an Nvidia. I had to switch the card from interrupt to polling in order to get a stable video player in Firefox. But now Firefox provides no audio. On the same system both MPlayer and Chromium handle audio and video without problem. But these also worked before I switched from interrupt to polling. The sysctl settings are: sysctl -a | grep snd device snd_cmi device snd_csa device snd_emu10kx device snd_es137x device snd_hda device snd_ich device snd_via8233 hw.snd.maxautovchans: 16 hw.snd.default_unit: 2 hw.snd.version: 2009061500/amd64 hw.snd.default_auto: 1 hw.snd.verbose: 0 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 sysctl -a | grep hdac irq264: hdac0:143 @cpu0(domain0): 2412 irq282: hdac1:179 @cpu0(domain0): 57 dev.hdaa.1.%parent: hdacc1 dev.hdaa.0.%parent: hdacc0 dev.hdacc.1.%parent: hdac1 dev.hdacc.1.%pnpinfo: vendor=0x10ec device=0x0892 revision=0x03 stepping=0x02 dev.hdacc.1.%location: cad=0 dev.hdacc.1.%driver: hdacc dev.hdacc.1.%desc: Realtek ALC892 HDA CODEC dev.hdacc.0.%parent: hdac0 dev.hdacc.0.%pnpinfo: vendor=0x10de device=0x0051 revision=0x01 stepping=0x00 dev.hdacc.0.%location: cad=0 dev.hdacc.0.%driver: hdacc dev.hdacc.0.%desc: NVIDIA (0x0051) HDA CODEC dev.hdacc.%parent: dev.hdac.1.polling: 1 dev.hdac.1.pindump: 0 dev.hdac.1.%parent: pci12 dev.hdac.1.%pnpinfo: vendor=0x1022 device=0x1457 subvendor=0x1849 subdevice=0x7893 class=0x040300 dev.hdac.1.%location: slot=0 function=3 dbsf=pci0:12:0:3 handle=\_SB_.PCI0.GP18.AZAL dev.hdac.1.%driver: hdac dev.hdac.1.%desc: AMD (0x1457) HDA Controller dev.hdac.0.polling: 0 dev.hdac.0.pindump: 0 dev.hdac.0.%parent: pci10 dev.hdac.0.%pnpinfo: vendor=0x10de device=0x0e0f subvendor=0x3842 subdevice=0x3733 class=0x040300 dev.hdac.0.%location: slot=0 function=1 dbsf=pci0:10:0:1 dev.hdac.0.%driver: hdac dev.hdac.0.%desc: NVIDIA (0x0e0f) HDA Controller dev.hdac.%parent: Can anyone shed some light as to why Firefox, and apparently only Firefox, has such difficulties with the Nvida setup? And provide some guidance on how to deal with them. -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail Unencrypted messages have no legal claim to privacy Do NOT open attachments nor follow links sent by e-Mail James B.
