Instead of looping the whole queue, the driver now loops on the first
invalid packet. In any case it will send a progress signal to its
client.
Fixes#1666.
With the introducation of the Audio_in session interface it makes
sense to rename the current available audio drivers. At the moment
only the dde_bsd audio_drv supports Audio_out as well as Audio_in.
The Linux audio_drv only supports Audio_out (there is no demand for
Audio_in support currently) but is renamed nonetheless to make it
easiert to write generic run scripts.
Issue #1644.
The driver is now able to record audio samples. In contrast
to playback it has to be enabled explicitly by setting the
configuration attribute 'recording' to 'yes'. Playback is by
default enabled but may be disabled by setting 'playback' to
'no'. Furthermore it is now possible to configure the mixer
from the configuration. For now, the interface used by vanilla
OpenBSD is just exported.
The following snippet shows how to enable and configure recording
on an Thinkpad X220 where the headset rather than the internal
mic is used as recording source:
! <start name="audio_out_drv">
! <resource name="RAM" quantum="8M"/>
! <provides>
! <service name="Audio_out"/>
! <service name="Audio_in"/>
! </provides>
! <config recording="yes">
! <mixer field="outputs.master" value="255"/>
! <mixer field="record.adc-0:1_source" value="sel2"/>
! <mixer field="record.adc-0:1" value="255"/>
! </config>
! </start>
In addition to selecting the recording source the playback as
well as the recording volume are set to 255 (maximum).
Information about the available mixers and settings in general
may be obtained by setting the 'verbose' to 'yes' in the config
node.
Issue #1644.
Unfortunatly, there is no support for any HDMI/DP based HDA codecs in
this driver. Therefore we try to filter out known devices (normally the
PCI device on 00:03.00). This could also be done in the platform_drv's
configuration by explicitly naming the BDF but for better or worse that
will not work when using a wildcard class like HDAUDIO which is done in
generic run scripts.
Issue #1644.
These audio drivers enable support for Intel HD Audio (Azalia) and
Ensoniq AudioPCI (ES1370) compatible soundcards. They are ported
from OpenBSD 5.7.
Fixes#1498.
