Guys/gals, I have been experiencing an odd problem with my NAS setup. I finally got things to work, sort of. I have a small FreeBSD 4-8-REL system running nasd (NAS 1.6). I want to connect to it via a separate machine on the network. Now, I CAN play simple .WAV files via auplay, and this works. I can also use auinfo to get the particulars of the server: alexandria# auinfo -audio gearbox:0 Audio Server: tcp/gearbox:8000 Version Number: 2.2 Vendor: Network Audio System Release 1.6 - VoxWare Vendor Release: 1 Min Sample Rate: 5000 Max Sample Rate: 44100 Max Tracks: 32 Number of Formats: 7 Formats: ULAW8 LinearUnsigned8 LinearSigned8 LinearSigned16MSB LinearUnsigned16MSB LinearSigned16LSB LinearUnsigned16LSB Number of Elem Types: 12 Element Types: ImportClient ImportDevice ImportBucket ImportWaveForm Bundle MultiplyConstant AddConstant Sum ExportClient ExportDevice ExportBucket ExportMonitor Number of Wave Forms: 2 Wave Forms: Square Sine Number of Actions: 3 Actions: ChangeState SendNotify Noop Number of Devices: 3 Device 0: Changable: Gain LineMode ID: 0x23 Kind: PhysicalInput Use: Import Format: LinearUnsigned8 Num Tracks: 2 Access: Import List Description: "Stereo Channel Input" Min Rate: 5000 Max Rate: 44100 Location: Left Right External Gain Percent: 50 Num Children: 0 Device 1: Changable: Gain ID: 0x22 Kind: PhysicalOutput Use: Export Format: LinearSigned16LSB Num Tracks: 2 Access: Export List Description: "Stereo Channel Output" Min Rate: 5000 Max Rate: 44100 Location: Center Internal Gain Percent: 50 Num Children: 1 Children: 0x21 Device 2: Changable: Gain ID: 0x21 Kind: PhysicalOutput Use: Export Format: LinearSigned16LSB Num Tracks: 1 Access: Export List Description: "Mono Channel Output" Min Rate: 5000 Max Rate: 44100 Location: Center Internal Gain Percent: 50 Num Children: 0 Number of Buckets: 0 However, if I attempt to use mpg123 or xmms with the NAS plugin, the server hangs. After it hangs, I can no longer use auplay or auinfo. There is nothing in the log files to indicate what happened, it simply no longer does anything. When using xmms or mpg123, I don't hear anything - there isn't even a few bad samples, just silence. Now, I have verified that both mpg123 and xmms-nas can send audio data to my IBM Netstations. It's bad, but audible (probably due to the lack of CPU in the netstations). It doesn't appear to be related to sample size - as I have played 16-bit waves through auplay. Any ideas? Thanks, Seth Henry
