Broken ALSA output on rx51 #1231

Closed duxks closed 10 years ago

duxks commented 10 years ago

On a Nokia N900, which has the rx51 sound card (really, SoC), mpv can't play audio with the alsa ao since commit b3f9d3750b8e1e627008758181aa98a6c788e7cd.

A log of trying to play a file follows; the relevant error is (according to a bisect), "[ao/alsa] Unable to set buffer time near: Invalid argument".

I asked in IRC a while ago (near 0.4.x, when this first cropped up) and heard that this likely indicates a pretty awful sound card. I can believe that, but sadly there's no way to swap out the sound card on a SoC, and this is a really painful regression. Hopefully it isn't too painful to fix; thanks.
