The following reply was made to PR i386/52428; it has been noted by GNATS. From: jimd@siu.edu To: Martin.Kaeske@Stud.TU-Ilmenau.DE Cc: freebsd-gnats-submit@FreeBSD.org Subject: Re: i386/52428: pcm0 reported twice: onboard AC97% Date: Mon, 19 May 2003 11:44:16 -0500 (CDT) Thank you for the update. On a Dell GX240 FreeBSD-4.8-RELEASE system, I see two pcm devices: grep pcm /var/run/dmesg.boot pcm0: <CMedia CMI8738> port 0xdc00-0xdcff irq 11 at device 7.0 on pci2 pcm1: <Intel 82801BA (ICH2)> port 0xcc40-0xcc7f,0xc800-0xc8ff irq 10 at device 31.5 on pci0 pcm1: <Analog Devices AD1885 ac97 codec> pcm1: measured ac97 link rate at 55922 Hz cat /dev/sndstat FreeBSD Audio Driver (newpcm) Installed devices: pcm0: <CMedia CMI8738> at io 0xdc00 irq 11 (1p/1r/0v channels duplex) pcm1: <Intel 82801BA (ICH2)> at io 0xc800, 0xcc40 irq 10 bufsz 16384 (1p/1r/0v channels duplex) When I start Gnome2 "Volume Control" on said Dell GX240, I see two Cards, and the controls do indeed affect the two different sound devices seperately. In my situation as reported, I see only one pcm device, and only one "Volume Control" card. I had assumed that this was because of a lack of some support for the onboard AC97. In the Dell-GX240 kernel, I added: #PCI sound card support device pcm # for PnP cards #options PNPBIOS # enable PnP BIOS searching If I remember correctly, you are correct that cat /dev/sndstat currently only returns one device. I will try kldload-ing "snd_ich.ko" tonight and see what that does. Is there a MANual page or HANDBOOK entry for "snd_ich". I couldn't find one (I did read the MANual page for "snd"). Thank you.
