I get a lot > of distortion on my sound card if it is. not at all. no matter whether they're at 20%, 60%, 80%, 100%, the sound i absolutely *sheit*... previous discussion at [1] i wanted to record some sample from line out to show you guys, but *of course* now it is working. with alsa, that is. and now i can't break it anymore. yeah, but the problem is (a) that there is still another system with the same problem, and (b) experience tells me that the problem is going to come back... more diagnostics... if i insmod the trident.o module instead of alsa (but not having started alsa before that since the last reboot), it loads without errors: kernel: Trident 4DWave/SiS 7018/ALi 5451,Tvia CyberPro 5050 PCI Audio, version 0.14.9d, 02:14:17 Jan 8 2002 kernel: PCI: Found IRQ 11 for device 00:01.4 kernel: trident: SiS 7018 PCI Audio found at IO 0xcc00, IRQ 11 kernel: ac97_codec: AC97 Audio codec, id: 0x414c:0x4326 (Unknown) kernel: ac97_codec: AC97 Modem codec, id: 0x5349:0x4c21 (Unknown) but /dev/dsp doesn't accept any data, it's behaving like a FIFO that isn't being read. echo anything > /dev/dsp simply waits forever sox, mpg123, xmms et al. pretend to be playing but, no sound comes out, and the song never advances so i removed the trident modules... if i then start alsa, the sound at least works, even though it's distorted. and after alsa has been started (and stopped), trident loads as before, but now sound works too, albeit with heavy distortion. nevertheless, there seem to be no differences between the distortions of trident.o and alsa. so i went to the other system and recorded some samples through line out: [2] is monty python's "message for you sir" wave file played back, and [3] is miles davis' all blues played from mp3. both files are less than 30kb if you wish to have a listen... as you can hear, it's disgusting. and then i decided to finish this email, having left off for recording the samples when i wrote the echo anything > /dev/dsp line above, but now, for god's sake, simply loading trident.o through kmod on the other machine produces crisp sound -- for the first time ever! and the original machine also works. great. what was that about murphy's laws and the repairman??? anyway, i'll post again when problems reappear, for now this is for the archives... 1. http://lists.debian.org/debian-user/2001/debian-user-200112/msg04770.html 2. http://diamond.madduck.net/monty.mp3 3. http://diamond.madduck.net/miles.mp3 -- martin; (greetings from the heart of the sun.) \____ echo mailto: !#^."<*>"|tr "<*> mailto:"; net@madduck don't hate yourself in the morning -- sleep till noon.
