Hi,

I successfully tried to flash the firmware of my TP-Link WR1043ND. Everything works fine excepting MPD. If I try to start the music playback different MPD clients I get disconnected and nothing else happens. Using aplay for testing if the audiointerface works results in a positive result. wink Here's my mpd.conf:


music_directory        "/usb"
playlist_directory        "/usb/playlists"
db_file            "/usb/tag_cache"
log_file            "/usb/mpd.log"
pid_file            "/usb/run/mpd/pid"
state_file            "/usb/lib/mpd/state"

bind_to_address        "192.168.2.9"

I played with the mpd.conf and now I get the following error. I think that's the point. Maybe the alsa.conf is not correct? Can anyone help?



ALSA lib pcm_direct.c:1605:(snd1_pcm_direct_parse_open_conf) The field ipc_gid must be a valid group (create group audio)

@Schmafu

How have you installed mpd, because if I want to install it, their would be too much libaries and so the space of the Router is too less.

Thank you very much!

You have to compile it by yourself otherwise it won't work. wink

Ok...

Could you please post your config file of mpd?

Would be very helpful.

Now I have the "polish" Image (Gargoyle 1.3.5 + Backfire 10.3.1-RC3)  and extended the space to the usb stick.
I have a USB-Hub 1.1 with the following devices:

It looks like you have enabled OSS support but you have to enable alsa support. Maybe you could try playing a wav-file using aplay?

Thank you for your response.

Now I activated ALSA again.

following outcome with mp3:

...muss leider erst mal ein wave file auftreiben sad

Vielen Dank für die Hifle!

Hello,

I am trying to get a package of mpd with all supports of mediafiles.

Would their be one?

Thank you very much!

The discussion might have continued from here.
