I am getting right channel sound only from my sound cards in FreeBSD 4.2 (i.e. only the right speaker plays any sound). Using 'mixer vol 100:0' I get no sound at all from either speaker. I have tried with two different sound cards, an Ensoniq 1371 (PCI) and an SB 32AWE (ISA-PnP). I have tried multiple programs, including xmms and cdplay, playing to dsp0 or dsp1 (depending upon which card). Even a cat directly to dsp0 or dsp1 produces the same problem. 'uname -a' gives me: FreeBSD triangle-13.engr.wisc.edu 4.2-RELEASE FreeBSD 4.2-RELEASE #0: Mon Feb 19 13:32:43 CST 2001 'cat /dev/sndstat' gives me: FreeBSD Audio Driver (newpcm) Feb 19 2001 13:31:56 Installed devices: pcm0: <AudioPCI ES1371> at io 0xcc00 irq 9 (1p/1r channels duplex) pcm1: <SB DSP 4.13> at io 0x220 irq 5 drq 1:5 (1p/1r channels duplex) I enabled these devices by recompiling after adding the following lines to my kernel conf file: device sbc device pcm The relevant lines from dmesg are: pcm0: <AudioPCI ES1371> port 0xcc00-0xcc3f irq 9 at device 9.0 on pci0 sbc0: <Creative SB16/SB32> at port 0x220-0x22f,0x330-0x331,0x388-0x38b irq 5 drq 1,5 on isa0 pcm1: <SB DSP 4.13> on sbc0 It isn't a problem with the sound cards, as both worked fine before being put into the FreeBSD box. Also, the speakers, using the same cables, play fine when attached to a Windows box. Does anyone know what might cause something like this?
