A >> new patch is at: >> http://people.freebsd.org/~marius/t4dwave_M5451_32-bit.diff Hi Thanks for the patch, I've applied it and the driver seems to load properly: pcm0: <Acer Labs M5451> port 0x900-0x9ff mem 0x424000-0x424fff at device 8.0 on pci0 pcm0: <Analog Devices AD1881A AC97 Codec> pcm0: [GIANT-LOCKED] pcm0: [ITHREAD] Unfortunately, the actual "playing sound part" is not going too well. When I do e.g. : rc@ds9000:~ $ mpg321 03\ Wonderful\ Night\ \(feat\ Lateef\).mp3 High Performance MPEG 1.0/2.0/2.5 Audio Player for Layer 1, 2, and 3. ... Playing MPEG stream from 03 Wonderful Night (feat Lateef).mp3 ... MPEG 1.0 layer III, 192 kbit/s, 44100 Hz stereo I sometimes get some seconds of sound, but most of the time only silence or a short burst of static, and then pcm0:virtual:dsp0.vp0: play interrupt timeout, channel dead appears on the console. I tried to evade some layers of complexity by trying: rc@ds9000:~ $ sox 10-the_white_stripes-take_take_take.mp3 10-the_white_stripes-take_take_take.raw rc@ds9000:~ $ cat 10-the_white_stripes-take_take_take.raw > /dev/dsp0.0 cat: stdout: Invalid argument This didn't output anything audible, though I'm not even sure if it should work. As it worked for Gheorghe, chances are that I'm doing something wrong/different: - the driver is built directly into the kernel, I'm using sparc64/conf/GENERIC with minimal modifications: [root@ds9000 /usr/src/sys/sparc64/conf]# diff GENERIC SNOOSNOO 24c24 < ident GENERIC --- > ident SNOOSNOO 242a243,245 > > device sound > device snd_t4dwave - kernel built like this: 102 make buildkernel KERNCONF=SNOOSNOO 103 make installkernel KERNCONF=SNOOSNOO Thanks for your time & best regards Christian
