Dotaz: Audigy2ZS notebook pcmcia - mplayer nehraje audio stopu ac3/dts v 6ch

[Shidoshi]

Muj problem spociva v tom ze mi pri nastaveni /etc/mplayer/mplayer.conf pri zadani nasledujicich radku nejde prehrat audio vubec ani mp3/ac3/dts ...

ao=alsa:device=surround51
channels=6

- pri nastavenem default nastaveni mi prehraje jen 2ch mp3 audio stopy nicmene pri videu s ac3/dts to nehraje vubec... ao=alsa
channels=6

Nepouzivam zadnej zvukovej server, mam fc6.x86_64 a Enlightenment DR17. Popravde receno skousel sem nastavovat $HOME/.asoundrc mnoha spusobma taky sem hledal spustu konfiguraku ale na mplayer moc nemeli vliv nedari se mi rozbehat prostorovej zvuk pres mplayer aby ac3/dts zvukova stopa v 6ch hral a skutecne v 6ch a ne 2ch.

Pri pokusu o speaker-test mi to vyhodi neco jako tohle

# speaker-test -c 6 -D surround51

speaker-test 1.0.14rc1

Playback device is surround51
Stream parameters are 48000Hz, S16_LE, 6 channels

Podobnou hlasku hazi i mplayer pri tomhle nastaveni.

Co spravi:
speaker-test -c 6 -D surround51:2

[Petr Šobáň]

Jseš si jistej že se to nepokouší přehrávat třeba modemem atd.... ?

Koukni co máš v /etc/asound.conf případně ho smaž a když to nepomůže tak ho znovu vytvoř s správnými položkami.

Tady sou vystupy. Na ten /etc/asound.conf sem total zapomel skusim se s nim jeste pohrat. Ikdyz se mi to nastaveni v tom conf zda dobry. Jo jinak vystup mam spravni protoze vsechny zvuky mi v poho jdou amarok, xmms, psi atd.... jen mplayer nechce hrat prostorove...

[Shidoshi]

Tak trocha pozde ale lepe nez nikdy :) . Problem vyresen tak hodim sem i reseni. Stacilo se pohrat s nastavenim alsa => /usr/share/alsa/alsa.conf

Nastavit tyto parametry:

defaults.ctl.card 1
defaults.pcm.card 1
defaults.pcm.device 0

[dustin]

Zajímalo by mě, co tedy bylo první zařízení alsy, můžeš sem dát výstup 'aplay -l'. Díky.

[Shidoshi]

Pri prehravani ac3 je to v pohode ale pro dts uz to prohazuje kanaly [aspon u me] ale da se to vyresit pomoci pan.

downmixing 6-channel PCM

A tady je vypis aplay -l

Takže v DD 5.1 je to OK, a v DTS 5.1 jsou přehozené kanály? To by spíše ukazovalo na chybku v dekódovací knihovně DTS, výstupní zařízení alsy asi budou oba případy používat stejné (surround51? ).

[Shidoshi]

Tak s timhle to jede OK u AC3 pri DTS mi to prehazi kanaly center napr je na FL (front left) zatim to resim v konfiguraku s timhle... a jede to OK

af=pan=6:1:0:0:1:1:0:0:1:0.5:0.5:1:1

Pri ac3 u me mplayer vyuziva

Selected audio codec: [a52] afm: liba52 (AC3-liba52)

u dts je to

Selected audio codec: [ffdca] afm: ffmpeg (FFmpeg DTS)
