Hi,
Although PulseAudio recognises the sound cards, it is unable to
successfully initialise the corresponding output profiles on Void PPC
since the sound updates 7.4-rc1 [1]. The output via ALSA works.
Tested with the onboard HDA ATI SB sound device, Soundblaster LIVE
Player 1024 PCI card, AMD HDMI audio and with USB audio. Strangely
enough Pulseaudio can enable the sound devices on MintPPC32. I think
the latest sound updates are responsible for the issue on Void PPC.
I bisected last week [2] and ad28d2f607d1792c04531f2c5fd9ac0bf5bdcc9c
(ALSA: pcm: Serialize and check HW_REFINE ioctls) is the first bad
commit.
I was able to revert the first bad commit and this solved the issue. [2]
Then I created a patch for reverting the bad commit. [3]
Could you please check the sound updates 7.4-rc1? [1]
Thanks,
Christian

The sound-fixes-7.4-rc1 [1] don't solve the issue with PulseAudio on
Void PPC. We still need the sound patch [2] for reverting the bad commit.
