SYNOPSIS: device timeout(?) during the attempt to record anything Hello, I have two sound cards (only one is inserted into the box at any given moment) and am unable to make record properly any of them. The FreeBSD sources I use have been CVSUPed on Mar 24. FreeBSD isabase.philol.msu.ru 4.0-STABLE FreeBSD 4.0-STABLE #2: Sat Mar 25 21:31:20 MSK 2000 grg@isabase.philol.msu.ru:/usr/src/sys/compile/ISABASE i386 Now on the first card, it is ISA, behaves as a PnP card and is detected as Creative ViBRA16X. kernel config ------------- I have the following lines in my config: # (also tried with the this option commented out) options PNPBIOS # (also tried as "device pcm0 at isa? irq 5 drq 1 flags 0x15", to # try forcing the card be detected as non-PnP, with the only # effect of appearing "pcm1" instead of "pcm0" in dmesg) device pcm # (also tried with this device commented out # and also "device sbc0 at isa? port 0x220 irq 5 drq 1 # flags 0x15", # effect of appearing "sbc1" instead of "sbc0" in dmesg) device sbc boot loader config ------------------ In FreeBSD 3.4, I had the following command required to make my SB work in /boot/kernel.conf: pnp 1 0 os enable port0 0x220 irq0 5 drq0 1 drq1 3 Now it seems that it is not required and considered as error, though "man pnp" states the contrary. So I tried to boot with and without this command. BIOS setup ----------- All configurations have been tried with both "PnP OS installed: Yes" and "PnP OS installed: No", without any effect the behaviour of the card. dmesg ----- The messages in dmesg related to audio and PnP are as follows: 1) With "options PNPBIOS": unknown: <PNP0000> can't assign resources unknown0: <PNP0200> at port 0-0xf,0x81-0x83,0x87,0x89-0x8b,0x8f-0x91,0xc0-0xdf drq 4 on isa0 unknown1: <PNP0100> at port 0x40-0x43 irq 0 on isa0 unknown2: <PNP0b00> at port 0x70-0x71 irq 8 on isa0 unknown: <PNP0303> can't assign resources unknown: <PNP0800> can't assign resources unknown3: <PNP0c04> at port 0xf0-0xff irq 13 on isa0 unknown4: <PNP0c01> at iomem 0-0x9ffff,0xfffe0000-0xffffffff,0x100000-0x3ffffff on isa0 unknown5: <PNP0c02> at iomem 0xf0000-0xf3fff,0xf4000-0xf7fff,0xf8000-0xfbfff,0xfc000-0xfffff on isa0 unknown6: <PNP0a03> at port 0x294-0x297,0x4d0-0x4d1,0xcf8-0xcff,0x480-0x48f,0x4000-0x403f,0x5000-0x501f on isa0 unknown7: <PNP0c02> at port 0x208-0x20f on isa0 unknown: <PNP0501> can't assign resources unknown: <PNP0700> can't assign resources unknown: <PNP0401> can't assign resources unknown: <PNP0501> can't assign resources sbc0: <Creative ViBRA16X> at port 0x220-0x22f,0x330-0x331,0x388-0x38b irq 5 drq 1,3 on isa0 sbc0: setting card to irq 5, drq 1, 3 pcm0: <SB DSP 4.16 (ViBRA16X)> on sbc0 unknown8: <Game> at port 0x201 on isa0 2) Without "options PNPBIOS": sbc0: <Creative ViBRA16X> at port 0x220-0x22f,0x330-0x331,0x388-0x38b irq 5 drq 1,3 on isa0 sbc0: setting card to irq 5, drq 1, 3 pcm0: <SB DSP 4.16 (ViBRA16X)> on sbc0 unknown0: <Game> at port 0x201 on isa0 Problems --------- Playback of .au, .wav, .mp3 works as expected. However, when I attempt to record an .au or .wav with the 'rec' program from sox, e. g.: grg@isabase.1:~$ rec a.au Send break (control-c) to end recording I cant interrupt the recording with pressing control-c one or several times: the "^C" is just printed on the terminal, and the program won't stop. If I press "^\" (quit), "^\" is printed, and there is no any effect for more than 3 seconds, and only after that I see "Quit - core dumped". The resulting file, a.au has zero length. There are no any messages on the console except: /kernel: pid 7403 (sox), uid 1001: exited on signal 3 (core dumped) It looks like device timeout for me, but whatever it is, I can't record anything. I tried to record 16-bit sound instead of default 8-bit, with the same effect. Also, I try to record using the 'lrecord' command from ESPS/waves+, a commercial software equipment compiled for Linux (lrecord states for Linux-record). lrecord worked for me on FreeBSD 3.4. Now I get the following: grg@isabase.1:~$ lrecord a.sd [then I press ^C] Problems writing samples at sample number 0 No samples collected! Now what? History -------- Both 'rec' and 'lrecord' worked for me for 8-bit and 16-bit 8 KHz sound on FreeBSD 3.4-STABLE. However, there were a strange message on the console just after starting rec or lrecord that looked something like: drq0 and drq1 swap: now 3 and 1 and just after finishing the recording: drq0 and drq1 swap: now 1 and 3 I have no idea if this is a problem at all, but on other machines with other sound cards there is no such a message. But also, there WAS another problem on FreeBSD 3.4-STABLE: If I recorded 16 KHz sound instead of 8 KHz, it seemed to work OK, and the sound was actually recorded. However, if I used tools for drawing dynamic spectrograms of the sound (such as sound processing tools from ESPS) they showed no spectral information above 4 KHz. This is the evidence of that the hardware actually recorded the audio at the frequency rate of 8KHz, though software thought it put the hardware in 16KHz mode (when you make a spectrum, for a 8KHz sound, you only can see spectral information up to 4Khz, for 16KHz sound you can see it up to 8KHz, and so on). If I recorded a 16KHz sound on another machine copied it to my machine and visualized using the same tools, I could see spectral information up to 8KHz, as expected. So the was apparently pcm driver problem in FreeBSD 3.4-STABLE. I have installed 4-STABLE that early in hope that new pcm driver would work better, and as result I cannot record audio at all. What now? Please help. P.S. I don't know the exact model name of this SB16 Vibra: it was preinstalled in that newly bought machine and the only documentation for the SB was a four-page paper with intructions on how to install Windows drivers for it. -- === Grigoriy Strokin, Lomonosov University (MGU), Moscow === === contact info: http://isabase.philol.msu.ru/~grg/ === To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
