reassign 582840 linux-2.6
retitle 582840 PCM channel missing from OSS mixer API
thanks
Okay, I investigated some more and this seems to be happening with the
latest Debian testing kernel (2.6.32-5-amd64) as well as with latest
stable upstream (2.6.34). Since other apps such as Xfce Mixer are also
affected (with both kernel versions) I'm re-assigning the bug to the
kernel maintainers.
Kernel people, I hope you agree with me that this is an ALSA issue
rather than an aumix bug. Basically, the OSS compatible mixer API
doesn't seem to export a PCM channel anymore. There is a channel PCM2
though which, in my case, can only be set to 0 or max. From what it
looks like, OSS PCM2 corresponds to the "Headphone" toggle in ALSA
mixer apps (setting PCM2 to 0 unchecks "Headphone" in xfce4-mixer,
setting it to anything else checks it).
In case it matters, I'm using snd-hda-intel with the following hardware:
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio
Controller (rev 02)
Subsystem: ABIT Computer Corp. Device 1085
Flags: bus master, fast devsel, latency 0, IRQ 22
Memory at fdff8000 (64-bit, non-prefetchable) [size=16K]
Capabilities: [50] Power Management version 2
Capabilities: [60] MSI: Enable- Count=1/1 Maskable- 64bit+
Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00
Kernel driver in use: HDA Intel
This one might on some level be related to #571253 but since I know
nothing about ALSA's internal magic that's just a wild guess :)
Also, feel free to reassign back to aumix if you disagree.
cheers
