| 10:56 | <ltspuser_78> Hello
| |
| 10:57 | <gvy> hi
| |
| 10:58 | <ltspuser_78> can anybody help me with a rather peculiar problem regarding LTSP and sound on Thin clients?
| |
| 11:00 | <gvy> well I'm not using ubuntu/debian variants but there might be generic troubles...
| |
| 11:04 | <ltspuser_78> I'm running LTSP with Edubuntu 12.04 on a VM (Esxi) and have a mix of hp t5720 and t5520 thin clients connected. They all work fine with one exception
| |
| 11:05 | the sound only works on the t5720's and NOT on the t5520's
| |
| 11:05 | they both have the same audio cards (AC97)
| |
| 11:05 | <gvy> ac97 is a name of a standard IIRC, the chips might be vastly different
| |
| 11:06 | look up how to log in locally at the clients (requires root password set in whatever remote root filesystem the clients do get)
| |
| 11:06 | then get a console login there (ctrl-alt-f1 or f2, root, password)
| |
| 11:07 | then run "lsmod | grep snd" to get the list of ALSA drivers loaded and compare these
| |
| 11:07 | if alsa-utils package is installed (should be) then alsamixer should present a text UI where the main interest is Master and PCM ("m" mutes/unmutes, arrow keys change, esc exits)
| |
| 11:08 | might be just zero level on some of these two channels
| |
| 11:08 | <ltspuser_78> ah right, lemme try this straight away
| |
| 11:09 | <gvy> or the other way around, try booting the clients off a usbflash with a "live" version of a distro to verify that the drivers get loaded and there's no "simpler" problem of no hardware support
| |
| 11:09 | albeit that would be quite unexpected for these imho

| 11:18 | <ltspuser_78> how do i recognize the ALSA drivers in the lsmod output?

| 12:53 | <gvy> snd_ prefix
| |
| 12:55 | <alkisg> !localxterm
| |
| 12:55 | <ltsp> localxterm: Any applications that you launch on a thin client actually runs on the server, not on the client itself. If you want to open a program on the client locally, you can type 'ltsp-localapps <program>' in a run dialog or in a terminal. For example, 'ltsp-localapps xterm' to open a terminal running on the client.
| |
| 12:55 | <alkisg> ltspuser_78: try running `alsamixer` in a localxterm ^
