Both of these are new in 4.0-STABLE. I previously ran a variety of 3.X and 4.0-CURRENT kernels under which sound worked well with the pcm driver. 1: Playing .au files by 'cat foo.au > /dev/audio0' loses part of the beginning of the sound. Any .au file less than 1048 bytes produces only silence. [Note, I do not believe there is necessarily anything magic about 1048. It happens to be the size of the smallest .au file I have which makes any sound. The largest silent .au file is 1039 bytes] Larger files produce a period of silence, followed by two clicks, followed by the appropriate sound, followed by another click. I believe the sound produced has lost a leading amount of about one second. 2: The sound card does not accept audio signal from an external device connected to the line-in socket. Machine is a dual P-Pro 200 with on-board sound. Kernel is yesterdays 4.0-STABLE: FreeBSD 4.0-STABLE #2: Mon May 29 14:03:57 EDT 2000 Kernel config entry for pcm is: device pcm dmesg shows: pcm0: at port 0x534-0x537,0x388-0x38b,0x220-0x22f irq 5 drq 1,0 on isa0 unknown0: at port 0x200-0x207 on isa0 unknown1: at port 0x120-0x127 on isa0 unknown2: at port 0x300-0x301 irq 11 on isa0 No other device claims irq 5 (or 11) Any ideas?
