For a long time, I've wanted everyone to try out Richard Lovejoy's volume-adjustment kernel. I think it's the best thing since sliced bread.

But for many people, the barrier to trying it is the fact that they can't turn it on and off from the player's front panel. Well, with some help from several sources, I've now got a set of files that will allow you to do it:

http://www.oro.net/~tfabris/empeg/Picker_and_Voladj_for_Dummies.zip

This includes step-by step instructions for installing all of the files. It also integrates nicely with displayserver, if you want to use both. There's even a short discussion about the nature of dynamic compression. Finally, you can have the option of adjusting the parameters to voladj to tailor it to your liking.

Note that I didn't write any of the software included in the file, I just organized the files, wrote the instructions, and hacked up the shell scripts. The credit for the software goes to Frank Van Gestel, Richard Lovejoy, and Rex K. Perkins. Thanks, guys!

Enjoy!

Greetings!

May I recommend a FAQ entry - "Where to get all of the good programs / files?"

Okay, now that folks are running this, I have a question for everyone:

Does anyone get a "pop" on their audio outputs at the moment the choice is made at boot-up?

(Note: This seems to only happen when the choice is made at boot-up, not if you make the choice from the "quit" menu. It's also intermittent.)

This happened with Selecter, both on my Mark1 and my Mark2. Now it also happens with Franks ioctl-sender program. There's something happening when the Voladj code gets the ioctl message- a brief burst of noise comes out of the outputs.

Anyone else get this?

Ah, now we see why Tony has put in all the work on this stuff. It was just a cynical attempt to get other people to investigate a problem he was having himself...


Only kidding Tony, good work (as always).

You've seen through my cunning plan.

By the way... If anyone is trying to reproduce it, I wanted to say that in my case, it's only noticeable in the car, because that's where the amplification is turned up loud enough for it to be audible. When it's plugged in at home, the pop is usually too quiet to be heard.

Yes. The one I built with picker does this as well at bootup, but I haven't tried it from my menu off the quit yet. It's so minor, I haven't even really looked into it. (I guess the pop I had with the Mk 1 on shutdown for the brief time it was installed in dash got me used to things like this :-)

Funny, I just tried the link and it works fine. What OS/Browser are you using? Also, is it possibly a routing problem? What error are you getting? Can you PING or do a TRACERT to the web server?

Dow! Now it works. Am using Netscape 4.77 on WinNT. The server was giving a 401 error saying File not found.

Thanks for you quick response! especially since it seems it was a false alarm. Now I can get on with some more installation

Happy Easter

For anyone who's using my "Picker and Voladj for Dummies" instructions, I wanted to give an important update:

I've modified the instructions to include the alteration of the "reservecache" parameter in config.ini. I spent some time trying to report a player software bug, only to discover that it was my fault.

The replacement "init" that I use in the instructions causes bash to be loaded and stay in memory while the player software is running. Unless you free up a bit of cache space for bash, the player software can get low on memory and occasionally (in rare circumstances) glitch a little bit.

So, in the part of the instructions where you add the "[Menu]" and "quit=1" lines to the config.ini file, you also need to add "[startup]" and "reservecache=12" right after it.

(By the way, I'm aware of the other discussions related to Displayserver's performance with and without the reserved cache. What I discovered is unrelated to Displayserver-- there was a player bug that I could reproduce even if Displayserver wasn't loading at all.)

I have just updated the Picker and Voladj for Dummies file with some minor changes to the readme and a new version of the "ioctl" executable.

This is to make it compatible with version 1.03 of the player software. Note that this breaks compatibility with versions 1.02 and earlier.

The updated "ioctl" was compiled by Drakino, based on code written by Frank Van Gestel.

Well, if you want the Mark 1 ones, I consider that enough demand. Booting up the server now (it's a noisy beast im my cube, so it's off most of the time . Look for them later tonight (aka 3 hours from now tops).

The kernels for the Mark 1 are now up. Keep in mind I don't have a Mark 1 anymore, so I have no way of testing these. Please let me know if they work properly.

Well, the first (date) hit I got when searching for rubbing lamp was from muzza who said
"OK next wish said while rubbing old lamp" nearly a year ago (07/30/00) in this post .

After that it is you, in this post back in january.

I have updated my Picker and Voladj for dummies file again.

I have included a new version of the "voladj" ioctl utility, which has been modified by Richard to mute the mixer before applying its updates. This prevents a "pop" sound from coming out of the amplifier when you select it.

Unfortunately, my ISP is in the process of killing my web site and I can no longer update the files there. The web site itself will disappear shortly. (I'm not happy about this, anyone know a good US company with cheap web hosting that includes dial-up accounts?)

In any case, the new file is attached to this message if anyone wants it.

This error message means that, somewere along the line, you did not do the RO and ROM commands before rebooting the player.

I have done this on occasion, and I get the same error.

Every time I do it, I always have to ask someone what the correct command-line is to perform the FSCK to get the player back to normal again.

Anyone want to post the command once more so that I can make a permanent FAQ out of it?

Hi.

Well, it all depends on which partitions you get the error for. However, the following script should do everything for you on any player (be it MkI or MkII):

#!/bin/bash
export PATH=/bin:/sbin:/usr/local/bin:/usr/local/sbin
# start here if doing this manually:
umount -n /drive0
[ -e /proc/ide/hdb ] && umount -n /drive1
[ -e /proc/ide/hdc ] && umount -n /drive1
fsck -f /dev/hda4
fsck -f /dev/hda5
[ -e /proc/ide/hdc ] && fsck -f /dev/hdc4
[ -e /proc/ide/hdb ] && fsck -f /dev/hdb4
mount -o ro -n /dev/hda4 /drive0
[ -e /proc/ide/hdb ] && mount -n -o ro /dev/hdb4 /drive1
[ -e /proc/ide/hdc ] && mount -n -o ro /dev/hdc4 /drive1

Hmm. It was simpler when I did it before?

I just did RW then RWM, then one line to fix everything, then RO ROM'd again.

Hi Tony.

Hmm. It was simpler when I did it before?

It can be done in a simpler way, but rw/rwm then some line, then ro/rom is certainly not the way to go. The partition you want to check should not be mounted at the moment () of checking, and most certainly not mounted read/write. It is possible to check partitions that are mounted r/o, but do never check a partition that is mounted r/w.

Well, to make the long story short, if you are willing to take a little risk (of the system not noticing a fixed FS, which can be easily fixed by a reboot), you could boil that script down to:


#!/bin/bash
export PATH=/bin:/sbin:/usr/local/bin:/usr/local/sbin
# start here if doing this manually:
fsck -a -f /dev/hda4 /dev/hda5 /dev/hdc5


I just had the script check everything that could be checked, just to make sure.
Oh well, this is the point where I have to admit that I made a mistake in my previous post: I didn't check the actual device files on the empeg, and assumed /dev/hdb* was available on the MkII. Well, it isn't, so one should change any reference to /dev/hdb* to /dev/hdc*, but do not change the references to /proc/ide/hdb.

cu,
sven

The ability to switsh the voladj on and off is very good but i don-t like that the boot time is a lot longer now. Is it possible to disable the voladj choice on booting and retain this function in the menu? Actually it would be more logical if the menu function would be under Sound submenu and would be named Volume Adjustment or VolAdj.

Yes. You can alter the order of the "While" loop in the init script so that it runs the player first, before the picker. That means the player will boot with voladj always on, but then you can turn it off by selecting QUIT from the menu.

Instructions for doing this were somewhere else on the BBS already. Possibly somewhere down lower in this very thread. Have a look and see...

Actually it would be more logical if the menu function would be under Sound submenu and would be named Volume Adjustment or VolAdj.

If I could do that, I would. Unfortunately, it's not within my power. The player software is closed-source and I cannot alter its menu structure.

You can only Quit the player software so that it returns control to a different program (in this case, the shell script with the Picker).

Hey, at least we can be glad they gave us the "Quit" option, right?

Ok as i understand i can use the middle buttons to execute other programs or choose other options if i will change the settings in picker_list file.
Any ideas what cool things can be done with them ?
