Ubutnu:  9.04:  No Audio:  lost audio upgrading from 8.10 -> 9.04

Hi;

About two days ago I upgraded from Ubutnu 8.10 to Ubuntu 9.04.

In the process I lost all audio.    I don't know much about the guts of
Linux so any help I can get to get audio back would be greatly
appreciated.

Here is a part of my output that looks audio related from the lspci
command:

===================================================================
00:1f.3 SMBus: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M)
SMBus Controller (rev 02)
00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM
(ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 02)
02:00.0 Multimedia audio controller: Creative Labs SB Live! EMU10k1
(rev 07)
02:00.1 Input device controller: Creative Labs SB Live! Game Port (rev
07)
02:02.1 Multimedia controller: Brooktree Corporation Bt878 Audio
Capture (rev 11)
======================================================================

Running the command pulseaudio I got this output


==========================================================================
I: caps.c: Limited capabilities successfully to CAP_SYS_NICE.
I: caps.c: Dropping root privileges.
I: caps.c: Limited capabilities successfully to CAP_SYS_NICE.
N: main.c: Called SUID root and real-time and/or high-priority
scheduling was requested in the configuration. However, we lack the
necessary privileges:
N: main.c: We are not in group 'pulse-rt', PolicyKit refuse to grant
us the requested privileges and we have no increase RLIMIT_NICE/
RLIMIT_RTPRIO resource limits.
N: main.c: For enabling real-time/high-priority scheduling please
acquire the appropriate PolicyKit privileges, or become a member of
'pulse-rt', or increase the RLIMIT_NICE/RLIMIT_RTPRIO resource limits
for this user.
E: pid.c: Daemon already running.
E: main.c: pa_pid_file_create() failed.
=======================================================================



Then I tried these commands, but it didn't help get audio back.  I rebooted.

====================================================================
steve@Wisdom:~$ sudo usermod -G pulse-rt steve
steve@Wisdom:~$ sudo killall pulseaudio
steve@Wisdom:~$ pulseaudio
I: caps.c: Limited capabilities successfully to CAP_SYS_NICE.
I: caps.c: Dropping root privileges.
I: caps.c: Limited capabilities successfully to CAP_SYS_NICE.
W: alsa-util.c: Device hw:1 doesn't support 44100 Hz, changed to 32000
Hz.
W: alsa-util.c: Cannot find fallback mixer control "Mic" or mixer
control is no combination of switch/volume.
===================================================================

Again, I don't know much about linux, but I am will to try things to get
the sound working.

Thanks
