I have a laptop with the 7018 sis audio chipset. not sure how similar they are, but FWIW: sound seems to work fine under win2k, so i doubt its a h/w problem [maybe just poorly designed hw ;)]. However, in fbsd 4.8 i have to perform a lil tinkering to get sound working. The problem will be when i first reboot sometimes i can get 11 seconds of playback, and then it stops [sometimes i wont get any at all]. then after that initial 11, i cant get it to play again. things like restarted xmms/mplayer/whatever_sound/video_app doesnt work. Eventual frustration led to me play with hw.snd.maxautovchans and hw.snd.pcm0.vchans with xmms, i find i have to open up the app, then set both thos sysctl values to 4. kill xmms. check fstat |grep dsp. the sooner it reports that a dsp vchan is being used [even tho xmms is open] the better. as that seems to be the trick. sound will only work if i have a zombie process using one of the sound vchans. then i set the two sysctl values back to 0 [this is usually when the zombie process will appear. i notice getting xmms to hang will usually induce the zombie process]. now i can set the sysctl values back to 4, change the /dev xmms should use to something other than the one the zombie process is now claiming [otherwise xmms should report /dev/dsp as busy]. then i seem to be able to play all the mp3 and dvd i want. Also to note: i am able to play audio cd's fine w/out all this nonsense [i assume thast cuz the audio is being directly output, and not processed by bsd]. my dmesg| grep pcm is slightly different than yours, but hope this helps.. pcm0: <SiS 7018> port 0x3400-0x34ff mem 0x24003000-0x24003fff irq 5 at device 1.4 on pci0 pcm0: <Asahi Kasei AK4543 ac97 codec> On Wed, 28 May 2003 00:15:46+0200 Florent DANIEL<fdaniel-at-noos-point-fr@FreeBSD.ORG>(by way of Florent\ DANIEL<fdaniel@noos.fr>) wrote: > Hello, > > I can't get my onboard soundcard to work on FreeBSD 4.8-STABLE.
