I have a 24kHz/24bit wave file: $ file antani.wav antani.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 24 bit, stereo 48000 Hz My sound card supports this format, and so I can play it with 'aplay' $ aplay -v -D front:CARD=1,DEV=0 antani.wav Playing WAVE 'antani.wav' : Signed 24 bit Little Endian in 3bytes, Rate 48000 Hz, Stereo Hardware PCM card 1 'UA-1EX' device 0 subdevice 0 Its setup is: stream : PLAYBACK access : RW_INTERLEAVED format : S24_3LE subformat : STD channels : 2 rate : 48000 exact rate : 48000 (48000/1) [...] Actually that format is what my audio card *wants*! If I try to play a 16bit/44.1kHz file, alsa converts it to 24bit/44.1kHz (I can see that with aplay -v). But I have problems in playing the 24bit/44.1kHz file with mplayer: $ mplayer -ao alsa:device=hw=1.0 antani.wav ========================================================================== Opening audio decoder: [pcm] Uncompressed PCM audio decoder AUDIO: 48000 Hz, 2 ch, s24le, 2304.0 kbit/100.00% (ratio: 288000->288000) Selected audio codec: [pcm] afm: pcm (Uncompressed PCM) ========================================================================== [AO_ALSA] Format s24le is not supported by hardware, trying default. [AO_ALSA] Unable to set format: Invalid argument Failed to initialize audio driver 'alsa:device=hw=1.0' Could not open/initialize audio device -> no sound. Any clue? (I know I could use device=plughw=1.0. In this way, when mplayer tryes the default s16le after failing with s24le, the alsa "plug" plugin converts the audio again to s24le, which is what my card expects, and so it "works". But I don't want that downsampling.). Thank you! pl _______________________________________________ MPlayer-users mailing list MPlayer-users@xxxxxxxxxxxx https://lists.mplayerhq.hu/mailman/listinfo/mplayer-users
