dxs_support=1 produces garbled sound. dxs_support=4 works ok! iirc it didn't with the shared interrupt line, want me to try again? i'm not in the mood for rebooting right now if it needn't be. tried playing three 16-bit stereo 44.1 kHz streams via OSS-emulation in parallel, it works. amazing! >as default, ac97_clock is 48000, so you don't need to specify it. >a different ac97_clock shouldn't be given unless the chip is really >driven in that clock. ok, i was suspecting so. >> however, to enable analog output (only one present on the board) the >> mixer controls for 'headphone' not 'master' must be unmuted (volume >> and playback switch). since they aren't accessible from alsamixer this >> had me puzzling for a while. > >please show /proc/asound/card0/codec97#0/* files. follows at the end of this mail (module loaded with dxs_support=4). >thanks for the feedback. thanks for the quick answer. :) tim ps: `cat /proc/asound/card0/codec97#0/*` 0-0/0: VIA Technologies VIA1612A Capabilities : -headphone out- DAC resolution : 18-bit ADC resolution : 18-bit 3D enhancement : IC Ensemble/KS Waves Current setup Mic gain : +0dB [+0dB] POP path : pre 3D Sim. stereo : off 3D enhancement : off Loudness : off Mono output : MIX Mic select : Mic1 ADC/DAC loopback : off Extended ID : codec=0 rev=0 AMAP DSA=0 VRA Extended status : VRA PCM front DAC : 48000Hz PCM ADC : 48000Hz 0:00 = 6d50 0:02 = 8808 0:04 = 0808 0:06 = 801f 0:08 = 0000 0:0a = 801e 0:0c = 801f 0:0e = 801f 0:10 = 9f1f 0:12 = 9f1f 0:14 = 9f1f 0:16 = 9f1f 0:18 = 0808 0:1a = 0000 0:1c = 8000 0:1e = 0000 0:20 = 0000 0:22 = 0000 0:24 = 0000 0:26 = 000f 0:28 = 0201 0:2a = 0001 0:2c = bb80 0:2e = 0000 0:30 = 0000 0:32 = bb80 0:34 = 0000 0:36 = 0000 0:38 = 0000 0:3a = 0000 0:3c = 0000 0:3e = 0000 0:40 = 0000 0:42 = 0000 0:44 = 0000 0:46 = 0000 0:48 = 0000 0:4a = 0000 0:4c = 0000 0:4e = 0000 0:50 = 0000 0:52 = 0000 0:54 = 0000 0:56 = 0000 0:58 = 0000 0:5a = 8230 0:5c = 0010 0:5e = f7ff 0:60 = 0000 0:62 = 0000 0:64 = 0000 0:66 = 0000 0:68 = 0000 0:6a = 0000 0:6c = 0000 0:6e = 0000 0:70 = 0000 0:72 = 0000 0:74 = 0000 0:76 = 0000 0:78 = 0000 0:7a = 0000 0:7c = 5649 0:7e = 4161 ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
