USB Soundkarte Volumeregler

[wpte]

Finally I got a self-compiled version going (with alsa-support) - but the sound problem remains.

Is it possible, that this phenomenon stems from the fact, that the router does not provide enough power for an external 2,5" HDD and the soundcard? If I change the cable or if I plug inbetween a non-active HUB, the sound quality changes!

Or is it some real interference (in the physical sense) with the other usb device (hdd)?

How sensitive is the ASUS on USB-Port-position or the insertion of a hub?

hehe, yeah, could be a power problem.
I didn't thought that the soundcard would draw that much power.
The router has slightly less amps available on the usb ports than a real pc, that's why I also use a powered usb hub

(keine Ahnung, warum ich das jetzt alles auf englisch geschrieben habe - naja es ist spät)

Sorry, my German is a bit poor, that's why we sort of switched to english.
Reading German is ok, but I'm terrible at writing it

I can read it without google translate
but you know just as well as I do that english (or any other language) to german in translate gives you the worst sentences ever
Just as english to dutch

in the end pheidrias asked for help, I tried to help him, that's what this forum is all about.

Which is really !

Apropos: Hoping, that the sound-quality problems will disappear with the delivery of a powered USB-Hub, I'd like to come back to the original problem.

Do you think, this (http://www.synology-forum.de/showthr...Fernbedienung&) could work on our ASUS-Routers as well?

You might understand a little more C than me - so maybe you could have a look at the (small ;-) ) source file...

In fact, I assume, the forward/etc. buttons do work just like multimedia keys on "modern" keyboards...

I'm not sure if they are multimedia keys like on keyboards
This C program uses libusb, which allows you to compile this directly on your router if you have the appropriate packages installed:

ipkg install optware-devel
ipkg install buildroot

(takes some time to download)

that and the libusb library could do the trick

If it doesn't work out of the box, could you give me the output of these:

lsusb
lsusb -v

It gives info on your usb devices

Hi wpte!

mpdremote compiled without problems.
However, if I start it via

cd /opt/bin
./mpdremote_check.sh

I only get:

sh: pts/0: unknown operand

mpdremote (the compiled binary, also copied to /opt/bin) itself executed puts my ssh-terminal into nirvana - can't stop it via CTRL-D, CTRL-C or CTRL-X...

lsusb gives:

lsusb
Bus 002 Device 001: ID 1d6b:0001
Bus 001 Device 004: ID 041e:30d1 Creative Technology, Ltd
Bus 001 Device 003: ID 0bc2:2101 Seagate RSS LLC
Bus 001 Device 002: ID 0424:2502 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002

lsusb -v is attached.

[wpte]

hmmm yes, I just checked it myself

The implementation isn't that great either...

signal(SIGINT, endloop);
  signal(SIGHUP, endloop);
  signal(SIGTERM, endloop);

  while(loop) {
    memset(packet,0,sizeof(packet));
    ret = hid_interrupt_read(hid,0x82,packet,PACKET_LEN,1000);
    if( ret == HID_RET_SUCCESS ){
      if (packet[0] == 0x03) {
//        printPacket(packet,PACKET_LEN);
        if (handleKey(&packet[1]) == 0)
		break;
      }
    }
  }

he is using signals, so you *could* shut it down, however... that doesn't really happen now does it
why?

ret = hid_interrupt_read(hid,0x82,packet,PACKET_LEN,1000);

he waits for an interrupt... which doesn't happen
so either way, you stay in the loop as long as the interrupt doesn't return any answer.

so what needs to be done?
1. kick out the while loop and make the program fork into a "daemon mode"
2. probably some changes based on the usb data you gave me
I'll try to work on it in the weekend, is that ok for you?

Are you kidding? This would be GREAT!

I can try to assist you with stand-by, while you're coding ;-).

Could you read out of lsusb, wether the buttons are Multimedia-Keyboard-like?

THANKS A LOT,

It shows that the audio usb device also has a HID (human interface device).
Now that HID seems to be a keyboard kind of thing with "Generic Desktop Controls" that I believe are those generic play, pause, next, back buttons
There are several examples on the internet how to read them, so it shouldn't be to hard to cook something up

Hello!

I finally tested the system with an active USB-Hub and the sound quality was drasticly increased (although it wasn't as good as when directly connected to my laptop/PC)!

Now it's just the multimedia-buttons fun missing. Any news on this?

Thanks a lot,
pheidrias

Cool stuff!
It's supposed to read out the buttons.
I have: volume up, volume down, next, previous, play/pause
Apart from that I didn't see any other buttons in the usb dump.

I also fixed that the process stayed alive... forever.
The problem now is... I don't think I will read out the soundcard correctly. It has been over a year that I used libusb, so I have to read up on that first.

I did however re-feel the anger of using libusb again... I just find it a horrible library (to work with)
So right now I'd say I'm on 75% of completing it

For me, working with USB itself has always been a horrible thing. Never got all USB-devices at one time working in right speed etc...
Independent of the operating system in use, unfortunately...

Hi again! Do you think, you'll be able to pick yourself up to finish this horror thing? Now, after Halloween, this might be some easy thing to do?

Would be great,
pheidrias

[pheidrias]

Hi wpte!

Any news on this?
Maybe you could post the 75% you were able to finish until here and someone else could try to finish 'em?

Thanks,
pheidrias
