Bug#499381: two sound cards - vlc fails to open ice1712 : unable to set stream sample size and word order

[Michel Briand]

Package: vlc
Version: 0.8.6.h-1
Severity: normal

Hi,

I've two sound cards.

$ cat /proc/asound/cards
 0 [ICH5           ]: ICH4 - Intel ICH5
                      Intel ICH5 with AD1985 at irq 17
 1 [M2496          ]: ICE1712 - M Audio Audiophile 24/96
                      M Audio Audiophile 24/96 at 0xdf80, irq 23

[Kernel has a race problem: card order changes between boots...]

When selecting the sound card through the vlc gui menu, it doesn't
work on the chosen sound card (ICE1712), output this message:

[00000338] main audio output debug: looking for audio output module: 3 candidates
[00000338] alsa audio output warning: unable to set stream sample size and word order, disabling linear PCM audio

[00000338] main audio output debug: filter(s) 'fl32'->'s16l' 48000 Hz->48000 Hz Stereo->Stereo


and falls back to the other sound card.

When I specify explicitly the target sound card:

vlc --alsadev default:CARD=M2496 

It works!

Is there something to improve in vlc ?

Cheers,
Michel
