Mixer/sound driver volume levels and distortion
by Neil Sedger 19 Oct '07

19 Oct '07

Hi all, I have onboard AC97 sound, according to kmix my system automatically set itself up with the 'VIA 8237' driver, which is probably right. I have a good old analog connection to an amplifier. If I set master and PCM to 100% the volume is at a good level but is very distorted. If I move both down 'a bit' then the distortion goes away but it's all a bit unscientific as to how much that 'bit' is. If I leave PCM at 100% and move Master about it gets quieter but is always distorted. In Windows on the same hardware, setting all mixers to 100% seems to output a good, loud, non distorted sound, I'd guess at the 'line level' that my amp is expecting. Is there a setting somewhere in the (ALSA) driver to set the maximum output to 'line level' so I can set kmix at 100% and get good volume and no distortion? There is an 'External amplifier' switch in kmix but it appears to have no effect. I've had a good root around on Google and the answer appears to be 'turn the mixer volumes down a bit' - e.g.: http://alsa.opensrc.org/index.php/TroubleShooting#Sound_can_be_heard_but_it… There must be something more accurate? If the Windows drivers have some built-in setting can it be replicated? Cheers Neil

Viewing XML files
by Mark Rogers 19 Oct '07

19 Oct '07

I have some relatively large* XML files (about 3MB) which I need to work with (view certainly, edit would be nice). They're not formatted - there are no line breaks in the files - which means most of the editors I've tried to open them with have struggled, and FireFox took about half an hour to open one of them. What are good (preferably GUI) tools for this kind of thing? I'm on Ubuntu some Gnome-biased is great, but to be honest anything that does the job is great enough. The application which creates them can comfortably handle a valid reformatted file, so if the lack of formatting is lost on a save that's not an issue. I don't really want to have to preprocess the files to tidy them before opening, though, as the files change frequently. [*] Personally I find it hard to believe that 3MB is "large" in today's world, but I guess it is quite a long line if you're expecting line breaks. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG

Any good tools for generating HTML tables out there?
by Chris G 18 Oct '07

18 Oct '07

I'm using reStructuredText extensively for writing notes etc. that I can use both as written and by generating HTML from the .rst files so they can be viewed in a browser. However the table generation syntax in reStructuredText is a bit clumsy, 'simple tables' are OK but don't have row spans and I really want row spans, 'grid tables' can do anything but take a huge amount of effort to type. So, I'm after some simple way of generating HTML tables, preferably from some sort of text 'source' file that is itself reasonably readable. Has anyone here got any suggestions for anything like this? -- Chris Green

Re: [ALUG] usb printer not recognised

I occasionally have a similar problem with Slackware, (It happened again only yesterday), the computer does'nt 'see' the printer, I think it is that the USB plugs are'nt a very good fit. I usually have to unplug, re-plug, (and wiggle), and then reinstall, (sometimes up to five or six times before the computer 'sees' the printer and it succesfuly re-installs. -- J.R.

How to mount a CIFS file system as a user?
by Chris G 18 Oct '07

18 Oct '07

I want a simple way to mount a CIFS file system that I can run as a user. There seems to be considerable confusion between the mount man page and the mount.cifs man page as to what can be done and what can't be done. According to the mount man page I can add a line to /etc/fstab as follows (or something like, the syntax may well be wrong) :- //192.168.1.10/C /home/chris/xp cifs noauto,user 0 0 The 'user' option is supposed to allow a user to mount the file system. However if I say "mount /home/chris/xp" I get:- mount error 1 = Operation not permitted Refer to the mount.cifs(8) manual page (e.g.man mount.cifs) Referring to the mount.cifs(8) manual page as requested is not very enlightening! Running "mount /home/chris/xp" as root works (I have to admit I only just tried) so the entry in /etc/fstab must be about right. -- Chris Green

usb printer not recognised
by Jenny Hopkins 18 Oct '07

18 Oct '07

Hullo there, I've stuck an HP LaserJet 1018 onto a debian stable box. Printer only has usb connection. However, hp-probe says there are no devices found, and lsusb agrees with this. Other usb devices work on this computer, and the printer works on a different (ubuntu) computer. The cups web interface detected a new printer, saying it was on "hp:/usb/HP_LaserJet_1018?serial=KP110YP". Printing a test page just gives the syslog error "knossos kernel: usb 1-2: usbfs: USBDEVFS_CONTROL failed cmd hpiod rqt 161 rq 1 len 1 ret -110 Oct 17 11:36:10 knossos hpiod: invalid Device::DeviceStatus: Connection timed out hp:/usb/HP_LaserJet_1018?serial=KP110YP io/hpiod/device.cpp 818 Oct 17 11:36:10 knossos hpiod: unable to read Device::GetDeviceStatus: Connection timed out hp:/usb/HP_LaserJet_1018?serial=KP110YP io/hpiod/device.cpp 1081" Have I missed out some modules to install, perchance? I've done an inordinate amount of googling on the various errors and found very little of help, and am stumped. Thanks, Jenny

Webcam, what software?
by Chris G 17 Oct '07

17 Oct '07

This seems very stupid but I can't really work out what Linux software can do useful things with a Webcam. The obvious thing to want to do is to show what the webcam is seeing on the web. I have apache 2.2 running. Also, any good voip type applications that have both Linux and Windows versions anc can use a webcam for video phonecalls? Skype doesn't have video on Linux. -- Chris Green

Can any expert out there help with SASL?
by Barry Samuels 14 Oct '07

14 Oct '07

I run Postfix on Debian Testing and I originally set outgoing mail in my mailer (Balsa) to be SMTP localhost:25. I have the choice of sending external mail either through my ISP's mail server or my web site hoster's mail server. In my Postfix main.cf I had relayhost = (one of two mail servers) Before I changed ISPs recently I used to send my external mail through my ISP (unauthenticated) but then I changed to my web site hoster's mail server and mail was going out through them (also unauthenticated). When I changed ISPs recently I found that I could no longer send through my web site hoster's mail server and they say that's because it requires authentication. I don't know why it should have worked with my old ISP and the people who host my web site haven't offered any explanation. So I'm trying, and failing dismally, to use SASL for SMTP authentication. I followed these instructions http://linuxgazette.net/142/pfeiffer.html However if I now try sending mail with SASL set up authentication fails on whichever external mail server I use but I don't know why or how to find out why it's failing. Can anyone help with this? -- Barry Samuels http://www.beenthere-donethat.org.uk The Unofficial Guide to Great Britain
