Description Bill Sanford 2012-05-14 20:16:09 UTC 
Description of problem:
The alsamixer on the SPICE VM sees the playback device and does not see the capture device.

Version-Release number of selected component (if applicable):
RHEL 6.3

How reproducible:
100%

Steps to Reproduce:
1. Create a RHEL 6.3 VM in a RHEV-M ic155.2 environment.
2. From the SPICE client, run alsamixer to select sound card and set volume.
3. Launch SPICE VM and run alsamixer and see there is no "Capture" device.
  
Actual results:
The SPICE VM has no "Capture" device to set volume.

Expected results:
The SPICE VM has a "Capture" device to set volume.

Comment 1 Bill Sanford 2012-05-14 20:18:29 UTC 
I have tried a stand alone mic with one plug input and Clear Chat Pro - USB Headset/Mic.
Comment 2 Bill Sanford 2012-05-14 20:40:11 UTC 
The reason I put this in alsamixer, is that the same configuration but with a Windows 7 Guest, works.
Comment 3 Jaroslav Kysela 2012-05-14 22:05:06 UTC 
Please, attach output from 'alsa-info.sh --no-upload'.

Comment 5 Bill Sanford 2012-05-16 14:31:40 UTC 
This is the output from the SPICE guest.
Comment 6 Jaroslav Kysela 2012-05-16 14:38:47 UTC 
The ALSA PCM capture device is three, but the virtual HDA codec does not have any volume control for the capture path, so the mixer interface does not offer it.

Just run 'arecord -f cd a.wav' or any other PCM capture session to test the sound input on guest.
Comment 7 Bill Sanford 2012-05-16 17:44:04 UTC 
After about the third reboot of the VM, now it works.
Comment 8 Jaroslav Kysela 2012-05-16 17:53:48 UTC 
It means that in some boot cases the capture volume control is not present?

It appears like a bug. It would be good to attach also 'alsa-info.sh --no-upload' for the working state.
Comment 9 Bill Sanford 2012-05-29 18:29:41 UTC 
I just installed RHEL6.3-20120516.0 as a SPICE VM and I am not seeing this behavior. 

If this is an issue again, I will enter the bug with the files from 'alsa-info.sh --no-upload' in the working and non-working state.
