[regression] --audio-device doesn't work with ao=oss

[yurivict]

The argument -ao oss:device=/dev/dspN used to work. At some point options changed (https:/mpv-player/mpv/wiki/Option-replacement-list). It says --ao=oss:device => --audio-device (different semantics), but --ao=oss --audio-device=/dev/dspN doesn't play to that device.

[kevmitch]

I think the key is in the "different semantics". I don't have working OSS to test, but it's probably something more like --audio-device='oss//dev/dspN. Check with --audio-device=help for the exact argument required.

[yurivict]

This command doesn't even show the OSS devices

$ mpv --audio-device=help
List of detected audio devices:
  'auto' (Autoselect device)
  'pulse/oss_output.dsp0' (/dev/dsp0)
  'pulse/oss_output.dsp1' (/dev/dsp1)
  'pulse/oss_output.dsp2' (/dev/dsp2)
  'pulse/oss_output.dsp3' (/dev/dsp3)
  'pulse/oss_output.dsp4' (/dev/dsp4)
  'pulse/oss_output.dsp5' (/dev/dsp5)
  'oss' (Default)

'oss' shouldn't be the value for --audio-device. The correct values (/dev/dsp2, /dev/dsp3) aren't in this list.

[yurivict]

I think it doesn't make sense to disable the old argument syntax when the new syntax has show-stopper problems like this.

[kevmitch]

Does my "guess" of --audio-device='oss//dev/dspN work? That should cause the oss code to open the /dev/dspN file if I'm reading the code right. It looks like the oss driver just doesn't have much in the way of code for listing the devices.

[yurivict]

--audio-device=oss//dev/dspN doesn't work

[kevmitch]

Can you post a log generated with --log-file=verbose.log?

[yurivict]

oss driver can list devices by listing /dev/ directory and selecting dspN parts.

Pulse doesn't work for me either, --ao=pulse --audio-device=pulse/oss_output.dsp2 doesn't play anything. paplay --device=oss_output.dsp2 x.wav plays sound okay.

[kevmitch]

Ok, well it seems --audio-device is currently broken / ignored with oss. I'm looking at fixing this now. In the mean time, the --oss-device option seems to work fine. Just ignore the deprecation warning.

[yurivict]

This works, thanks!
