FreeBSD aspire1703 5.4-STABLE FreeBSD 5.4-STABLE #1: Mon May 16 17:01:16 CEST 2005 luigi.lauro at aspire1703:/usr/obj/usr/src/sys/ASPIRE1703 i386
>Description:
On my 'Acer Aspire 1703SM' (info link: http://gerda.univie.ac.at/freebsd-laptops/index.pl?action=show_laptop_detail&laptop=640 ), even if devices are correctly compiled into kernel (sound & snd_ich), even if board is correctly detected and configured by driver, I get no sound at all, no matter what (tried a few program, even tried a cat 'long filename' > /dev/dsp to no avail), no matter where (even tried to plug headphones into mic or headphones port), no matter how (tried to play with some sysctl variables as vchans & others, also tried to pump up ALL mixer entries to 100:100, still no sound).
Sound part of my ASPIRE1703 kernel configuration file:
device speaker
device sound
device snd_ich
dmesg output (trimmed):
pcm0: <SiS 7012> port 0x1800-0x187f,0x1c00-0x1cff irq 18 at device 2.7 on pci0
pcm0: <Avance Logic ALC202 AC97 Codec>
pciconf -lv output (trimmed):
pcm0 at pci0:2:7: class=0x040100 card=0x00281025 chip=0x70121039 rev=0xa0 hdr=0x00
vendor = 'Silicon Integrated Systems (SiS)'
device = 'SiS7013 PCI Audio Accelerator'
class = multimedia
subclass = audio
cat /dev/sndstat output:
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <SiS 7012> at io 0x1c00, 0x1800 irq 18 bufsz 16384 (1p/1r/32v channels duplex default)
>How-To-Repeat:
Buy an Acer Aspire 1700 (any version will do, they all share the same motherboard, chipset & sound card), install any version of FreeBSD 5.x (tried 5.1, 5.2, 5.3, 5.4), kldload or compile-in devices (sound & snd_ich) and try to get sound.
You won't get any.
