If anyone is sucessfully running VAT (LBL MBONE audio tool) over a SB16, I would appreciate some help figuring out what I am doing wrong. My configuration contains: #device scd0 at isa? port 0x230 bio # SB = SoundBlaster; PAS = ProAudioSpectrum; GUS = Gravis UltraSound # Controls all sound devices controller snd0 # SoundBlaster DSP driver - for SB, SB Pro, SB16, PAS(emulating SB) device sb0 at isa? port 0x220 irq 7 drq 1 vector sbintr # SoundBlaster 16 DSP driver - for SB16 - requires sb0 device device sbxvi0 at isa? drq 5 # SoundBlaster 16 MIDI - for SB16 - requires sb0 device device sbmidi0 at isa? port 0x330 # Yamaha OPL-2/OPL-3 FM - for SB, SB Pro, SB16, PAS device opl0 at isa? port 0x388 and pseudo-device vat_audio I think I made all the relevant devices: snd*, pcaudio and vat. The "vat" program (v3.4) runs but I get no sound and no indication of any on the meters. The "showaudio" program (from MetaMail) seems to play the first buffer OK, but I don't hear anything after that, although "printk" statements show the writes are issued. When "vat" runs, I see constant calls to DMAbuf_input_ready, which seems strange to me. I thought this should be called to read the mic. I don't see any calls to sound_write_sw or to the routines in vat_audio.c. I assume the audio packets are available, since machine I am trying to get "vat" working on is one end of a tunnel forwarding onto a net where other machines can pick up the audio. I assume I have some configuration problem, but the current sources fail linking because DMAbuf_start_input is declared "static" in dmabuf.c, which concerns me. I got the same behavior in 2.0-950412-SNAP. I am under the impression that the SB16 was not supported in 2.0, but would gladly try that if someone says it might work. The board, of course, is working fine under Windows 95 on the same system. Stephen A. Mattin Delphi Internet Services Corporation 1030 Massachusetts Avenue Cambridge, MA 02138 stephen@delphi.com
