Created attachment 115037 [details]
output of pacmd list

I have a Nokia BH-905i headset with both a2dp and HSP profiles. Full config attached.

I'm able to use the A2DP profile without problems, but when I try to switch to the HSP profile, I see the following in the logs:

backend-native.c: connect(): Function not implemented

I've obviously compiled with the native headset support. Not sure what the problem is. The only suspicious thing is that pacmd list-cards shows 'unknown', or sometimes 'no'.

headset_head_unit: Headset Head Unit (HSP/HFP) (priority 20, available: unknown)


I've seen bug #87284, and I don't think it's related as I'm on kernel 3.18.11:

Linux chichenitza 3.18.11-gentoo #1 SMP Sun Apr 12 13:57:29 BST 2015 x86_64 Intel(R) Core(TM)2 Extreme CPU X9650 @ 3.00GHz GenuineIntel GNU/Linux

I thought it might be a missing kernel driver but I think it's all there:

luciano@chichenitza /usr/src/linux $ zcat /proc/config.gz | grep _BT_

CONFIG_BT_RFCOMM=m
CONFIG_BT_RFCOMM_TTY=y
CONFIG_BT_BNEP=m
CONFIG_BT_BNEP_MC_FILTER=y
CONFIG_BT_BNEP_PROTO_FILTER=y
CONFIG_BT_HIDP=m
CONFIG_BT_HCIBTUSB=m
# CONFIG_BT_HCIUART is not set
# CONFIG_BT_HCIBCM203X is not set
# CONFIG_BT_HCIBPA10X is not set
# CONFIG_BT_HCIBFUSB is not set

# CONFIG_BT_HCIBTUART is not set
# CONFIG_BT_HCIVHCI is not set
# CONFIG_BT_MRVL is not set
# CONFIG_BT_ATH3K is not set

Finally, should mention I know this should work as I've used it a couple of years back when Bluez4 had native headset support. Also works with my android devices.

"Function not implemented" is an error from connect(), which is a libc function. The error happens when PulseAudio tries to connect to the SCO socket. I believe the bug is either in glibc or (more likely) in the kernel.

Comment 2 Luciano 2015-04-13 18:56:41 UTC

Yep, that's why I referred to bug #87284, but as I said, it's not the same regression I don't think, as I have kernel 3.18.11. Any idea on how to proceed? Should I raise this on the bluez/kernel mailing list?

Comment 3 Tanu Kaskinen 2015-04-14 10:18:29 UTC

I think the bluez mailing list would be a good place to ask for help.
