Hi! Sorry to bother you, but checking the archives provided no definitive answer, so I thought I'd ask instead. I'm running FreeBSD 4.2-RELEASE on a PC with LuckyStar K7VAT motherboard (http://www.lucky-star.com.tw/products/mainboard/k7vat.htm). Such board is based on the VIA KT-133 chipset and the (in)famous VIA VT82C686. Judging from what I've read so far, this kind of setup seems to work for some users, but not for others. Maybe someone can shed some light? I added the line "device pcm" in my configuration file (that's the only audio related entry there), compiled and installed the new kernel and at boot time I see: pcm0: <VIA VT82C686A AC'97 Audio> port 0xe400-0xe403,0xe000-0xe003,0xdc00-0xdcff irq 10 at device 7.5 on pci0 So far, so good. Then: # cd /dev; sh MAKEDEV snd0 # cat /dev/sndstat FreeBSD Audio Driver (newpcm) Jan 17 2001 19:50:43 Installed devices: pcm0: <VIA VT82C686A AC'97 Audio> at io 0xdc00 irq 10 (1p/1r channels duplex) However, "xmms" produces something which is similar to white noise but of course is not really white noise -- different songs produce different noise. On the other hand, "amp" fails altogether: $ amp 13stories.mp3 amp 0.7.6, (C) Tomislav Uzelac 1996,1997 THIS PROGRAM COMES WITH ABSOLUTELY NO WARRANTY PLEASE READ THE DOCUMENTATION FOR DETAILS Playing: 13stories.mp3 Properties: stereo 44100Hz Coding Method: MPEG1.0 layer3 Bitrate: 192kbit/s Unable to set required audio format Broken pipe At the moment the only application able to produce some sound is "xgalaga", although it starts with the error message "xgal.sndsrv: Couldn't set DSP rate"! Now, am I doing something wrong or there's no way to make sound work on my setup?
